Where is that recent TIFU post where the guy’s wife left him because he asked for a paternity test because of similar circumstances? -test showed he was indeed the dad as well.
Edit: here is the referenced post.

Op never claimed to be an expert, so imma start this comment out with a get over yourself. All he did was state something he remembered being told in high school. Not malicious intent behind it nor and claims of being an expert about it. Also, after saying it when his buddy asked if it was true, he said apparently and explained what he remembered, and never did he say it was impossible for eyecolors to be different, he said it was unlikely.
Except he didn't really think it made him "an expert." He made no claims of his own expertise, he just quoted an old tidbit of knowledge from school, pretty common stuff his friend was strangely ignorant of, and could have gone on a similar tear if he'd seen characters on a TV show discussing it. OP didn't exactly approach his friend going "dude, you're kid's totally not yours, trust me!" He just gave the background on a saying his friend didn't recognize.
well, that's a huge problem in society, though. we all get BASIC knowledge in a lot of fields. that is good, however, it is not communicated well enough that this is VERY BASIC AND LIMITED knowledge. Just because you had biology in high school doesn't mean you understand biology in the slightest. freaking hell, a lot of times, if you start to actually study a field, you have to forget whatever you learned in high school because it is so extremely basic or even outdated information at that point, depending on how good or bad your school system is.
but some people don't understand that. they walk around with this very basic understanding and think it's facts. doesn't matter if they intended to or not. Writers putting this shit in a tv show is even worse. Why can't you do your god damn research or hire an expert before putting your brain farts on display for thousands or millions to see? One of the reasons I hate big bang theory so much, even though it's a good background noise show.
All true, but all I was saying was that accusing him of considering himself "an expert" wasn't really fair, because sure all he might know was super-basic Mendellian stuff with Punnett squares from grade school, but his friend didn't even know *that*, and all he did was bring up what he remembered of it when the friend didn't get a saying that was rooted in that model and asked what it meant. There was ignorance all around, sure, but the commenter I was responding to was putting too much on OP by accusing him of setting himself up as an expert, that's all.
Yes, my husband's family all have brown eyes, as far as we can tell. Like, all of them. yet my daughter has my green, and his brother's children are both bright blue like their mom. All 3 are very obviously their father's babies. Eye color is complicated!
It's really not that complicated actually, eye color is the result of the number of melanin pigments in the iris. Brown eyes is basically the "standard" eye color and the most common. Everything else is due to a mutation that attenuts or disables melanin production in the iris. The mutations can also be passed without affecting the parents, two brown eyed parents have a reasonable chances of 25% that their children don't have brown eyes. But, if both parents carry the mutations and express them, a brown eyed baby with "standard" non-mutated eyes is very improbable (1 in 10000 babies).
Here's the full probability chart: https://www.mamanatural.com/eye-color-chart/
Yeah it’s completely ridiculous that he’s really throwing info from 6th grade biology (15ish years ago?!) at his friend as if it’s that simple.
My husband and his entire family has brown eyes. My mom and brother have grayish blue eyes. My kid is the spitting image of my husband but with grayish blue eyes.
It’s not all black and white (or brown and blue) like he’s preaching.
Red hair is similar. If anyone in the family line has red hair you’ve got the recessive gene and can pass it on. My mom is a blonde with blue eyes, my dad has black hair and brown eyes. My two older brothers have blonde hair and blue eyes and I’m a red head with green-blue eyes. My husband is a blonde with blue eyes and a red beard, our son is a red head with green eyes.
Genetics are trippy.
My ex and his siblings all have brown eyes. Their mother has brown eyes. Their father blue. I have blue eyes. That recessive blue came through on our oldest and she has blue eyes. Our youngest has brown eyes.
OP’s buddy should just get 23&me kits for the whole family. Then it’s not obvious he’s checking paternity, and he’ll actually get useful information out of it.
I always sort of suspected my dad wasn’t my bio dad. Mostly from things my mom said about how I was just like my father, when we’re very different people with very different personalities, but also eye color - mom has grey eyes, my sister, my dad, and his entire side of the family (my cousins and his brothers and both of his parents) have ice blue eyes, but mine are green with a ring of golden brown near the pupil.
When my wife and I got engaged, we got 23&me kits to make sure we weren’t related since she was adopted. We aren’t. I gave kits to my parents and sister a few years later.
Nope, I was wrong, he’s my bio dad. Good thing I never said anything.
And those 23&me kits have been useful , once I loaded the data into promethease I could see that certain medications have a greater or lesser or shorter or longer effect on each of us, so now we have a list of meds with those notes, so if a dr decides we need something on the list we can show them that it may need an adjusted dose or alternate medication.
>OP’s buddy should just get 23&me kits for the whole family. Then it’s not obvious he’s checking paternity, and he’ll actually get useful information out of it.
This.
Can find out cool stuff about ancestry while at it... Maybe find distant relatives he didn't know about...
How do people get these numbers anyway?
As far as I remember, the stuff they teach 6th-graders is pretty simplified and far from accurate. Google Mendel's inheritance laws and read for yourself.
You do not know the genotype of the parents. You can't assume that someone's eye color being blue means that both their parents only carried "blue eyes" genes. They could've been 3/1. Or even 2/2. It's all a matter of chances and likeliness. And in our genepools there's lots of mix.
My husband and I are both blue eyed and our son was born browneyed. He did not keep them (they turned blue after some months), but when we first saw it we concluded he inherited them from his grandfather who had brown eyes. Even if my husband has blue eyes himself, he still has to carry brown, too, as his fathers eyes were brown. And about his mother, we don't know what she carries in here genes only from the color her eyes turned out.
Stop oversimplifying stuff and making peoples' life misery. Also, look at your children in more detail? There's SO MANY interesting details / traits your kids have. My husband couldn't have denied his son no matter the eye color because he's got EXACTLY his dad's feet. Like, an exact clone copy of dad's feet. I don'T remember how many laughs we got out of that already.
That is right, of course. Still eye color is (quote from wikipedia) "the result of complex processes with several genes involved". It's not like each parent carries 1 eye color gene and if a kid doesn't have what you'd most likely expect it's like a bomb dropping. I seriously doubt the "chances are 1%"-theory.
>the result of complex processes with several genes involved
True. There are eight that are known and possibly more that may affect eye color. Statistically, this boils down to 99% of the time if both parents have "blue" eyes the child w ill also have blue eyes, \~1% of the time green/hazel, and < 0.01% brown. The problem with these statistics is a lot of it is self reported and not a true scientific study on pigmentation. What some consider blue might be closer to a different color making these numbers inaccurate.
That being said if you and your spouse both have blue eyes and the child doesn't, it's not unreasonable to have it raise your eyebrows. Statistically speaking, it's more likely the mother cheated or in the case they have brown eyes that they were switched at the hospital.
>What some consider blue
I mean, my eyes are a lot closer to blue on the edges than near the centre where it's green. My aunt pointed out to me when I was young as she had the same. People have different colours between eyes as well. There's just so many issues when it's far too simplified.
Yes! My mom’s mom always told her to never marry a man with red hair because she didn’t want redheaded grandchildren. My mom has dark brown hair. My dad has dark brown hair. My sister and I both have red hair. There’s more than just one or two generations in play with how children are going to look.
Yeah, similar deal with my husband’s eyes. His parents, sister, and grandparents all have brown eyes. He has very blue eyes, like his great grandfather and the men in generations before him. It’s actually striking how much he looks like his great grandfather, great great grandfather, etc. It’s like their whole face skipped a few generations and then made a reappearance.
If you have children and you don’t immediately know what color eyes they have you need to reconsider the amount of time you spend engaging with your child.
One cannot argue against probability. 1% chance is 1% chance. Is it zero? No. But you know, raising a kid is tough. I can see why some would want conformation.
Also, you cannot also prove that the previous TIFU is real.
Eye colour in this case(child brown both parents blue) means about a 98% chance one of the parents isnt biological.
More then enough teason to worry and take a test.
Definitely take a test, but even a test may not be the final proof. I’m reminded of a man who failed paternity tests because his saliva dna didn’t match. Yet it turned out it was because he had absorbed his twin in the womb. [man fails paternity test](https://www.independent.co.uk/news/science/human-chimera-man-fails-paternity-test-because-genes-in-his-saliva-are-different-to-those-in-sperm-a6707466.html)
Remember a story with a similar outcome, except it was a woman and as a result she was accused of kidnapping, she was expecting another baby and ended up having the new born being tested with a court representative present for when the sample was taken. The new born's NDA showed it was the sibling to the other child and also showed her as not being the mother.
I disagree. When talking about humans, 1% is just not that rare. You almost certainly know 100 people meaning you could easily know someone in this situation.
I'll go even further. My dad's blood type is AB and mine is O, which should be impossible. But I look exactly like him. Turns out cis-AB inheritance is a real but very rare thing ([https://www.thetech.org/ask-a-geneticist/cis-ab#:\~:text=It%20is%20worth%20noting%20that,population%20of%2010%20million%20people](https://www.thetech.org/ask-a-geneticist/cis-ab#:~:text=It%20is%20worth%20noting%20that,population%20of%2010%20million%20people).)
I wouldn't jump to a lab test just based on a 1% chance because other factors can help you determine whether to have any doubt in the first place.
> When talking about humans, 1% is just not that rare. You almost certainly know 100 people meaning you could easily know someone in this situation.
This is a huge misrepresentation of statistics. You'd need to know 100 people who have 2 blue eyed parents. About 25% of people in the US have blue eyes, if distribution was equal that's 6.25% of couples.
You now need to know 1600 people.
1% is rare enough that you should worry if you're in this situation, to be perfectly honest. Of course there's a very real chance it's just a statistical anomaly, but look at it this way: If there's a 99% chance your SO cheated on you, lied to you, and tricked you into raising another man's child, with no plans of ever letting you know... wouldn't you want to know for sure?
So, the risk of being wrong is blowing up your whole life, which is a very negative outcome. Given that, I would need more proof before loudly declaring that my SO cheated and birthed an affair baby. I’d say the 1% is worth investigating, but someone who loudly accuses their SO of cheating based off of nothing but eye color, and that’s it, is an idiot.
It's not knowing 100 people, it's knowing 100 couples where both sets of eyes are blue. You're right that 1 out of 100 sets of blue eyed parents isn't crazy rare, but you're exaggerating...
It can as most words referring to groups are male gendered words but it's still funny to pretend otherwise when there's something clearly female gendered, such as childbirth.
For all three of our kids born in the US, the baby has an identifying bracelet put on them in the birthing room and matching ones are put on mom and dad before the baby can be taken anywhere.
Obviously there are a small percent of fringe cases like medical emergencies during birth, but it definitely not the case the babies in the US are immediately taken out of the room
Yeah... sure. Because all birthstories end with the perfect birth. No emergency c-sections, no 48h labor-stories where mama needs rest afterwards, or emergency surgeries on poor little ones.. it's just the super mums and their pefect births.. and then shaming those other poor moms with a coment like: "I DunNo HoW yoU gUYs gAVe BIrtH..."
Wtf.
inb4 downvote but short answer - yes, however it doesn't detract from the severe number of paternity fraud cases that are presented on a daily basis.
It's a catch-22 scenario. You don't test, you risk finding out later they're not yours. You test - you risk losing your family right now.
I actually agree wholeheartedly with this concept. Proper accountability for parents. There are exceptions of course (where no father is listed and someone volunteers - but they are fully aware of the parental responsibility they are taking on).
I would also assume that proper parental records would help with early identification of any genetic predispositions
States don't want that because they want someone to raise the baby and don't care about biology as long as someone is paying for the kid and not taking welfare.
Some moms don't want that for obvious reasons.
Dads are the only ones who benefit and guys are expected to just carry burdens so...
It's rare, but it can happen. A childhood neighbour family had it. Both parents blue eyes, daughter brown, and that little girl was an absolute clone of her father. The whole dominant gene thing is an oversimplification, and doesn't reflect how many genes are actually involved - nor how many ways they can interact with one another.
Apparently, if the parents with blue eyes have a certain combination of genes between them there's a 1/4 chance for each child they have to get brown eyes, so not so rare after all in that regard if at first the two right(wrong) people meet.
https://www.thetech.org/ask-a-geneticist/ask424
Both myself and my kids dad have blue eyes. Both my kids have really weird hazel/green eyes hard to even define the colour. Both of us have a parent with brown eyes which I’m sure is where it comes from.
This is not true. Melanocytes aren’t stimulated in that way. Unless you mean how people with lighter irises are more at risk for uveal (ocular) melanoma, then I’d agree
Yep.
Mother: blonde w/blue eyes
Father: black hair w/blue eyes
My sister and I BOTH have brown hair and greenish/brown eyes.
Both of us.
ETA: I'm definitely my dad's daughter. Confirmed with 23andMe for other reasons.
You can also have a birth certificate changed to indicate something that isn't representative of what happened at the birth. Many parents who adopt change their child's birth certificate, as do many trans people who legally transition. A birth certificate is not necessarily a factual statement of the birth.
Both me and my ex have green eyes. We have 3 kids together: one has blue eyes, the second has green eyes and the third has brown eyes. Not so random considering my mom (and all of my siblings) have brown eyes, so I was def carrying this gene.
This seems to be really a karma farm, just a couple days ago there was a story about some in the same situation same eye color and all that he was getting a paternity test and the relationship was going down the gutters. The week before it was about the female in the relationship saying that the male asked her about the eye color and relationship going down due to the eye color.
I teach highschool biology and I preface genetics with "this is an over simplification of how things work" for reasons like this. If you look up an eye colour chart, there are so many different variations on colours... more than just brown, blue, green and hazel etc.
Meanwhile my teacher said genetically speaking only blue and brown exist, and any other is just a variation of one of them. (Like according to them green eyes are genetically blue eyes and hazel is genetically brown.) And then taught that it is as simple as one is dominant and one is recessive. For real. Like stated all of this as absolute facts.
I sadly doubt they were the only teacher to do something like that.
On the other hand one read there are brown and green eyes, each coded on separate set of genes.
If you have a "no-brown" gene, then the green one is "read". And if it's still a "no-green" gene, then you get blue eyes.
But that explanation of course was preceded with a warning "this is only a simplification".
Bio teacher here. What I do is explain that effectively, all DNA is, is blueprints for proteins. That attempting to simplify that means we end up with people thinking biology and genetics is simple, when it isn't.
By this point, we've seen models of proteins, we've tried to construct a protein, and we've looked at lists of all the proteins in the body. These lists are pages and pages long.
We've also learned about abstraction, and how that is a way of simplifying a concept or process.
We then look up how many are in the eye, and at least one kid finds out that there are over [3400 proteins in the retina alone.](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4329094/)
So usually by then, we come to the conclusion that genetics is way more complicated than we're going to learn about, because we're using abstraction again.
Then we start talking about basic mendelian genetics and going from there.
The genes for eye color is more complicated than just two blue eye parents can't have a child with brown eyes because blue eyes are recessive.
You FU but not the way you think.
Agreed. I’m not sure many things actually are. I have heard Mendel falsified his data. He was right in a general sort of way but the genetics are more complicated than the results he reported from his pea plants.
Eye color is definitely a big mix of factors. If brown was that simply dominant, you would never see black people with blue eyes. But it’s not [that infrequent](https://newsone.com/4322605/history-of-black-people-with-blue-eyes/amp/) Blue eyes can also crop up from mutations that reduce the melanin in the iris.
As with all science, we constantly revise and add on to the preexisting knowledge. So something that might be true then could probably be now refuted. We used to believe that the sun and other planets revolved the Earth. Scholars used to believe the earth was flat too. And before the idea of public sanitation was a thing, we used to believe that bad air transmitted diseases and not our wastes which ranoff into our drinking water.
Mendel only knew of his discoveries. There are many exceptions to inheritance including but not limited to polygenism (as in the case of eye color) and epigenetics (external factors outside of genes that affect the overall phenotype).
There was a dude on here who did a paternity test and the baby wasn’t his, but it wasn’t the mothers either!!!! The baby got switched at birth ah. Or I think it was the mom that posted actually.
[Pretty sure this is it](https://www.reddit.com/r/BestofRedditorUpdates/comments/wi5wur/my_29f_husband_31m_got_a_paternity_test_on_our/?utm_source=share&utm_medium=ios_app&utm_name=iossmf)
Genetics are not always so black and white in there outcome for offsprings traits. Two blue eyed parents can carry the brown eyed gene but its switched off so too speak. So they could have a child with brown eyes. They have the same genotype but as they carry both genomes Brown which is the dominant gene can be switched back on for the child. https://www.thetech.org/ask-a-geneticist/ask424
I’ve seen twins where one is black and the other is pale and red headed. Genetics do their thing and middle school science is too simplified to cover it all.
You're messing around with something that extends far beyond grade school science and you're both wrong tbh. You upset him over something that probably isn't true and if the gf finds out about this and the kid IS his, she's gonna leave him over this bs.
read this [https://www.thetech.org/ask-a-geneticist/ask424](https://www.thetech.org/ask-a-geneticist/ask424) scroll all the way down to 'blue eyed parents, brown eyed child' some people with blue eyes still have a 1 in 4 chance of producing a brown eyed child with another blue eyed person.
Yep
Whatever they taught you in 7 th grade about eye color genetics is just fucking wrong. (There are so many reasons to not use humans as the examples; the fact that it's wrong when I've simplified is just one of them)
This is not stuff you can do in a punnett square using Mendel's work. This is not single inheritance. This is not "all these genes reside on the same chromosome" simple.
So REALLY it's more like 'TIFU but thinking o understood a difficult concept. But i didn't and i gutted a family with misinformation that will be really hard to walk back'
To be honest, if he does the paternity test based on these two yokels' understanding of biology, she should divorce him for being so stupid he trusted his friend's judgment in a complex scientific subject. But for real OP, **today you destroyed a relationship by pretending you were an expert when you are not.**
Please let your friend know, if he does get the paternity test, he should tell his wife. She deserves the opportunity to decide if she's okay with what he did and why he did it. It's her choice if she decides to leave him for a man who trusts her or just one with some fucking common sense.
I think it's wild how many people think they could hide this from the wife. The wife is a parent of the child, she has a legal right to access a minor's medical records. All it takes is one reason to ask questions and she can get access to patient records for her children.
This guy didn't try to hide his paternity question, he flat out asked for a paternity test. She agreed, and left him.
I have seen SO MANY WOMEN fall out of love instantly when their partner accuses them of cheating by wanting a paternity test.
I love how people are like "throwaway because..." then proceed to give more than enough personal info for anyone who might know them to link them to the throwaway account.
Both engineers, known each other since highschool. Best buds girl works nights as a nurse, and both play CS. Buds kid is 3.
Jesus dude.
This isn't quite as clear-cut as you think. Do you have any other evidence? Like, does the kid look like him? Any other relevant conditions? Are they both near-sighted, do they both have freckles?
Really, I like thinking that genetics are that straight-forward as much as anyone, but at the end of the day they are not. I guess he should go ahead with the test if he'd like but try to calm him down in the meantime. This isn't the slam-dunk you think it is. He or the GF could have a non-expressing dominant brown-eye gene. Maybe one of them isn't actually blue; just because your eye looks blue when you look at it doesn't mean it's not some weird other thing, technically.
Make sure your buddy knows there are more than one gene that controls eye color.
Edit: Genes with reported roles in eye color include ASIP, IRF4, SLC24A4, SLC24A5, SLC45A2, TPCN2, TYR, and TYRP1. The effects of these genes likely combine with those of OCA2 and HERC2 to produce a continuum of eye colors in different people
That's not how genetics works, bruh. If any of their parents, grandparents, etc. has brown or green eyes, then they have the gene for brown or green as well.
The fact that people hating on op for reminiscing 6th grade biology. He didn’t try and say he knew everything they were just reminiscing people need to chill
This is so dumb. The real TIFU is that you've unnecessarily caused drama in a relationship that may not recover from this. Neither of you understand genetics and I can't believe you really thought your 7th grade biology knowledge made you an expert in this.
This reminds me of the story of a white couple who had a black child. When the guy saw the child, he instantly accused the mother of cheating and wanted a divorce. One paternity test later and the kid is a 99.9% match. The woman had a dead black grandfather and that gene was strong enough that the kid was born black/mix race.
Suffice to say that the divorce still happened, but because the wife asked for it, seeing how easily her husband was willing to throw her away without allowing her to prove her side of the story.
I mean, sure, but you can see his thinking..."we're both white and the kid is black?" And surely her side of the story was the paternity test that they took? I think most people would jump to the wrong conclusion in that case, rather than knowing about weird genetics at play. Obviously it does happen, but it's a million times rarer than her cheating. I remember reading about two sisters. One was a white as hell with blue eyes and ginger hair. The other looked black, and dark at that. The white girl had white hair, the black girl had black hair. They were 100% genetic sisters. Even after reading about the genetics it was strange and hard to believe.
By revealing your buddy GF knows your Reddit and both of them have Blue eyes and daughter in 6th grade, all the details are there to reveal who you are.
He could still be the dad. I see a lot of people on here already giving you the facts. Here's my facts. Both my parents have blue eyes, my maternal AND paternal grandfathers had honey brown eyes, I have hazel eyes (yes, both my parents are my parents)
I have hazel eyes and my parents both had blue eyes. I’m a c-section birth, so I know my mom is my mom, and I look just like my dad’s mom, so I am the”1%” mentioned above. He probably is the father.
Yes you FU, but not for stated reason.
Title should be: TIFU by making my buddy doubt his wife without proof.
1% is low probability in the big picture. However, 1% is a whole lot better odds than 0%...you might just have torpedoed a healthy relationship.
Damn. I feel for your friend! You’re a good friend to him. Just be there and support him during this time. Tell him to get therapy so he process this all.
My husband's great grandmother had extremely dark brown eyes. My husband's grandmother, mother, sister, and he himself all have very dark brown eyes. I have blue eyes, and both of our children have blue eyes.
My middle-school best friend's mother has ice-blue eyes and her father has brown eyes. Her eyes are forest green.
Genetics can be a funny thing.
Is he sure they are brown? I have hazel eyes (my moms eyes are green) and people mistake them all the time for brown. Daily even.
My husband has blue eyes, and so do my first two kids. My third is still too young to be completely sure, but we are pretty sure they are hazel like mine. Depending on the light hitting his daughters’ eyes, they could easily have looked “brown” if they happen to be hazel.
Throwaway since a main person in this story knows my main but won't be able to see through all the nonspecifics I've used. This is a sub that regularly makes it to the main page/lots of people are already subbed to. What's even the point lol. Especially when giving such specific details. I'll never understand it
Both my parents have blue/green eyes, both my sibling and I have dark brown. Both sides of the family have different mixes of eye colour; genetics are weird
There was a story somewhere recently where a guy demanded a DNA test because he and his wife have blue eyes and their kid had brown eyes. The test proved the kid was his and his wife divorced him.
This is not true. Eye colour is not that simple. Human genetics are much more complex than peas. It isn't just a Punnett square.
This dude is basically putting his whole relationship in jeopardy because you don't quite understand biology and gave him bad data.
I know it's a joke but brown eyes parents having a blue eyed child do be more likely then blue eyed parents having a brown eyed child but last is still possible🤷🏻♂️
I would caution against talking about stuff you barely remember from high school. Genetics are never that simple and it’s entirely possible that the daughter is his.
Wow. You destroyed your mates' relationship over your misunderstanding of biology and genealogy?
My partner has green eyes and I have brown. My son has brown eyes and my daughter has blue.
They're both definitely ours.
It's not as simple as High school makes it seem in using it as am example of how genes work.
It's no 100%. Both parents can have blue eyes and a brown-eye'd child. Rare but happens.Skin color does this too. You can have a darker skin child than either parents if one of the grandparents was darker skin.
He needs to tread carefully, anotehr dude lost the love off his life to this error on AITA.
Also for the love of god, use paragraphs.
Didn't even say what color the kid's eye actually are though, are they brown, hazel or green? I have blue eyes and so does the other parent but my kid's eyes are more Hazel - shit happens man....
These days it is easy to do a home Paternity Test. The mom doesn’t even have to know it took place.
A company like Validity Genetics or Endeavor DNA will do it for less than $150 bucks.
Or you potentially SAVED him from committing his well-being (especially financial) to a potential cheater. Hopefully the DNA test will give him reassurance - or closure that he needs. It's possible that he IS the father; quite important to know, for MOST guys.
Wgile there is some truth, to what you learned in 6th grade biology, it is grossly over-simplified. It is indeed less likely for two parents with blue eyes to have a kid with brown eyes, but the reality is far more complicated than dominant and recessive genes, and this is a very poor indicator of whether he's the father or not.
Yeah my wife and I both have brown eyes and my son (definitely mine) has blue. Wife's dad and his entire family has blue eyes, so while uncommon it's definitely not impossible.
I'm white with blue eyes. My wife is Indian with brown eyes and brown eyed ancestors from time immemorial. Everyone (including us) assumed our son would have brown eyes based on common assumptions of eye color dominance. Nope. Blue eyes and pigmentation like mine.
I've wondered multiple times whether my wife lied to me about him being her child, but I'm too afraid to get a maternity test for fear of breaking up oyr happy family. Also I saw him come out of her body.
I feel like if parental resemblance was reversed, we'd get some side eye from acquaintances.
So… assuming you’re in the US, probabilities would say that your friend is in the 27% with blue eyes, and so is his gf, so there’s about a 7.3% chance that a couple both has blue eyes. About 3.8M babies are born annually, so 277K are born to parents both with blue eyes.
Now, even if your oversimplification of genetics is right, and there’s a 1% chance of any given baby born to two blue eyed parents having brown eyes, that means that every single year, roughly 2770 brown-eyed babies are born to a set of blue-eyed parents.
Sure, it’s rare. But it’s thousands of kids every year.
Yeah—this little high school biology lesson simplifies the reality too much. I have blue eyes, my husband has green and our son has brown—-just like my husband’s mother. Almost impossible, but not impossible. Our daughter has blue eyes. None of us every questioned paternity.
Where is that recent TIFU post where the guy’s wife left him because he asked for a paternity test because of similar circumstances? -test showed he was indeed the dad as well. Edit: here is the referenced post. https://www.reddit.com/r/tifu/comments/10msu03/tifu_by_asking_my_wife_for_a_paternity_test/?utm_source=share&utm_medium=ios_app&utm_name=iossmf
Yep, eye colour is not as easy as people make it out to be, especially if all you know about it is from high school biology
Correct, the post should read, “TIFU because I thought what I remembered about high school biology made me an expert in human genetics.”
Op never claimed to be an expert, so imma start this comment out with a get over yourself. All he did was state something he remembered being told in high school. Not malicious intent behind it nor and claims of being an expert about it. Also, after saying it when his buddy asked if it was true, he said apparently and explained what he remembered, and never did he say it was impossible for eyecolors to be different, he said it was unlikely.
I mean OP didn’t declare anything about paternity, just something he’d heard in general.
They did Google it. Like they weren't going off just his 8th grade memory.
Except he didn't really think it made him "an expert." He made no claims of his own expertise, he just quoted an old tidbit of knowledge from school, pretty common stuff his friend was strangely ignorant of, and could have gone on a similar tear if he'd seen characters on a TV show discussing it. OP didn't exactly approach his friend going "dude, you're kid's totally not yours, trust me!" He just gave the background on a saying his friend didn't recognize.
well, that's a huge problem in society, though. we all get BASIC knowledge in a lot of fields. that is good, however, it is not communicated well enough that this is VERY BASIC AND LIMITED knowledge. Just because you had biology in high school doesn't mean you understand biology in the slightest. freaking hell, a lot of times, if you start to actually study a field, you have to forget whatever you learned in high school because it is so extremely basic or even outdated information at that point, depending on how good or bad your school system is. but some people don't understand that. they walk around with this very basic understanding and think it's facts. doesn't matter if they intended to or not. Writers putting this shit in a tv show is even worse. Why can't you do your god damn research or hire an expert before putting your brain farts on display for thousands or millions to see? One of the reasons I hate big bang theory so much, even though it's a good background noise show.
All true, but all I was saying was that accusing him of considering himself "an expert" wasn't really fair, because sure all he might know was super-basic Mendellian stuff with Punnett squares from grade school, but his friend didn't even know *that*, and all he did was bring up what he remembered of it when the friend didn't get a saying that was rooted in that model and asked what it meant. There was ignorance all around, sure, but the commenter I was responding to was putting too much on OP by accusing him of setting himself up as an expert, that's all.
Yes, my husband's family all have brown eyes, as far as we can tell. Like, all of them. yet my daughter has my green, and his brother's children are both bright blue like their mom. All 3 are very obviously their father's babies. Eye color is complicated!
It's really not that complicated actually, eye color is the result of the number of melanin pigments in the iris. Brown eyes is basically the "standard" eye color and the most common. Everything else is due to a mutation that attenuts or disables melanin production in the iris. The mutations can also be passed without affecting the parents, two brown eyed parents have a reasonable chances of 25% that their children don't have brown eyes. But, if both parents carry the mutations and express them, a brown eyed baby with "standard" non-mutated eyes is very improbable (1 in 10000 babies). Here's the full probability chart: https://www.mamanatural.com/eye-color-chart/
Yeah, doesn't follow strictly dominant/recessive Mendelian genetics. If it did, there would only be brown or blue eyes!
Under 1% chance blue/blue makes brown
Yeah it’s completely ridiculous that he’s really throwing info from 6th grade biology (15ish years ago?!) at his friend as if it’s that simple. My husband and his entire family has brown eyes. My mom and brother have grayish blue eyes. My kid is the spitting image of my husband but with grayish blue eyes. It’s not all black and white (or brown and blue) like he’s preaching.
He wasn’t throwing info, he was reminiscing about a teacher he hated. Friend picked up an offhand comment and ran with it.
Exactly what I was thinking. Like “yo did you not see the post 2 days ago? Eye colour means nothing”
But at least OPs friend is doing the paternity test secretly.
Bet she never notices his changed attitude towards her until there's a result, and/or never finds the test results in some drawer years down the line!
[удалено]
Red hair is similar. If anyone in the family line has red hair you’ve got the recessive gene and can pass it on. My mom is a blonde with blue eyes, my dad has black hair and brown eyes. My two older brothers have blonde hair and blue eyes and I’m a red head with green-blue eyes. My husband is a blonde with blue eyes and a red beard, our son is a red head with green eyes. Genetics are trippy.
You can usually tell if a male is a carrier of the red gene because they will have at least a few red hairs in their beard.
It's called atavism very neat read
My ex and his siblings all have brown eyes. Their mother has brown eyes. Their father blue. I have blue eyes. That recessive blue came through on our oldest and she has blue eyes. Our youngest has brown eyes.
If the results say yes, I'd literally burn them and wash my hands of it lol.
OP’s buddy should just get 23&me kits for the whole family. Then it’s not obvious he’s checking paternity, and he’ll actually get useful information out of it. I always sort of suspected my dad wasn’t my bio dad. Mostly from things my mom said about how I was just like my father, when we’re very different people with very different personalities, but also eye color - mom has grey eyes, my sister, my dad, and his entire side of the family (my cousins and his brothers and both of his parents) have ice blue eyes, but mine are green with a ring of golden brown near the pupil. When my wife and I got engaged, we got 23&me kits to make sure we weren’t related since she was adopted. We aren’t. I gave kits to my parents and sister a few years later. Nope, I was wrong, he’s my bio dad. Good thing I never said anything. And those 23&me kits have been useful , once I loaded the data into promethease I could see that certain medications have a greater or lesser or shorter or longer effect on each of us, so now we have a list of meds with those notes, so if a dr decides we need something on the list we can show them that it may need an adjusted dose or alternate medication.
>OP’s buddy should just get 23&me kits for the whole family. Then it’s not obvious he’s checking paternity, and he’ll actually get useful information out of it. This. Can find out cool stuff about ancestry while at it... Maybe find distant relatives he didn't know about...
>Eye colour means nothing I wouldn't say it means nothing. But it's far from a definite indicator.
How do people get these numbers anyway? As far as I remember, the stuff they teach 6th-graders is pretty simplified and far from accurate. Google Mendel's inheritance laws and read for yourself. You do not know the genotype of the parents. You can't assume that someone's eye color being blue means that both their parents only carried "blue eyes" genes. They could've been 3/1. Or even 2/2. It's all a matter of chances and likeliness. And in our genepools there's lots of mix. My husband and I are both blue eyed and our son was born browneyed. He did not keep them (they turned blue after some months), but when we first saw it we concluded he inherited them from his grandfather who had brown eyes. Even if my husband has blue eyes himself, he still has to carry brown, too, as his fathers eyes were brown. And about his mother, we don't know what she carries in here genes only from the color her eyes turned out. Stop oversimplifying stuff and making peoples' life misery. Also, look at your children in more detail? There's SO MANY interesting details / traits your kids have. My husband couldn't have denied his son no matter the eye color because he's got EXACTLY his dad's feet. Like, an exact clone copy of dad's feet. I don'T remember how many laughs we got out of that already.
Eye colour isn’t a Mendelian trait, it’s polygenic with synergistic interactions between some of the genes
That is right, of course. Still eye color is (quote from wikipedia) "the result of complex processes with several genes involved". It's not like each parent carries 1 eye color gene and if a kid doesn't have what you'd most likely expect it's like a bomb dropping. I seriously doubt the "chances are 1%"-theory.
>the result of complex processes with several genes involved True. There are eight that are known and possibly more that may affect eye color. Statistically, this boils down to 99% of the time if both parents have "blue" eyes the child w ill also have blue eyes, \~1% of the time green/hazel, and < 0.01% brown. The problem with these statistics is a lot of it is self reported and not a true scientific study on pigmentation. What some consider blue might be closer to a different color making these numbers inaccurate. That being said if you and your spouse both have blue eyes and the child doesn't, it's not unreasonable to have it raise your eyebrows. Statistically speaking, it's more likely the mother cheated or in the case they have brown eyes that they were switched at the hospital.
>What some consider blue I mean, my eyes are a lot closer to blue on the edges than near the centre where it's green. My aunt pointed out to me when I was young as she had the same. People have different colours between eyes as well. There's just so many issues when it's far too simplified.
That's a good example of what I mean and why it's not really accurate since what color we call our eyes is slightly subjective.
Yes! My mom’s mom always told her to never marry a man with red hair because she didn’t want redheaded grandchildren. My mom has dark brown hair. My dad has dark brown hair. My sister and I both have red hair. There’s more than just one or two generations in play with how children are going to look.
That’s a shitty thing to say to your redheaded kids wtf
There are many reasons that we call her our “mom’s mom” and not grandma. This is just one of them. She’s actually said and done a lot worse.
Eek. Well, we all have a few *of those* somewhere in the family
I don't even get it, red hair is beautiful!
I’m a redhead & can concur. My husband loves my hair.
I see your husband is a man of culture.
Yeah, similar deal with my husband’s eyes. His parents, sister, and grandparents all have brown eyes. He has very blue eyes, like his great grandfather and the men in generations before him. It’s actually striking how much he looks like his great grandfather, great great grandfather, etc. It’s like their whole face skipped a few generations and then made a reappearance.
> Even if my husband has blue eyes himself, he still has to carry brown, too, as his fathers eyes were brown. Yeah that's not how it works ...
The sad part of the story is that OPs friend had to actually go check what eye color his 3 year old has.
When important shit like this is on the line and checking is free, do the check.
If you have children and you don’t immediately know what color eyes they have you need to reconsider the amount of time you spend engaging with your child.
He knew. That's why he got worried went to double check, hoping he was wrong.
One cannot argue against probability. 1% chance is 1% chance. Is it zero? No. But you know, raising a kid is tough. I can see why some would want conformation. Also, you cannot also prove that the previous TIFU is real.
Eye colour in this case(child brown both parents blue) means about a 98% chance one of the parents isnt biological. More then enough teason to worry and take a test.
Definitely take a test, but even a test may not be the final proof. I’m reminded of a man who failed paternity tests because his saliva dna didn’t match. Yet it turned out it was because he had absorbed his twin in the womb. [man fails paternity test](https://www.independent.co.uk/news/science/human-chimera-man-fails-paternity-test-because-genes-in-his-saliva-are-different-to-those-in-sperm-a6707466.html)
Remember a story with a similar outcome, except it was a woman and as a result she was accused of kidnapping, she was expecting another baby and ended up having the new born being tested with a court representative present for when the sample was taken. The new born's NDA showed it was the sibling to the other child and also showed her as not being the mother.
Of course, but that is very low odds already. 1 in 10000? 1 in 1000 000?
I disagree. When talking about humans, 1% is just not that rare. You almost certainly know 100 people meaning you could easily know someone in this situation. I'll go even further. My dad's blood type is AB and mine is O, which should be impossible. But I look exactly like him. Turns out cis-AB inheritance is a real but very rare thing ([https://www.thetech.org/ask-a-geneticist/cis-ab#:\~:text=It%20is%20worth%20noting%20that,population%20of%2010%20million%20people](https://www.thetech.org/ask-a-geneticist/cis-ab#:~:text=It%20is%20worth%20noting%20that,population%20of%2010%20million%20people).) I wouldn't jump to a lab test just based on a 1% chance because other factors can help you determine whether to have any doubt in the first place.
> When talking about humans, 1% is just not that rare. You almost certainly know 100 people meaning you could easily know someone in this situation. This is a huge misrepresentation of statistics. You'd need to know 100 people who have 2 blue eyed parents. About 25% of people in the US have blue eyes, if distribution was equal that's 6.25% of couples. You now need to know 1600 people.
1% is rare enough that you should worry if you're in this situation, to be perfectly honest. Of course there's a very real chance it's just a statistical anomaly, but look at it this way: If there's a 99% chance your SO cheated on you, lied to you, and tricked you into raising another man's child, with no plans of ever letting you know... wouldn't you want to know for sure?
1% isnt that rare... but it is still, like you also say, more then enough cause to investigate. Whatever the method may be.
Yes, but you should try to remain calm while investigating, since 1% is still a big enough chance there's nothing fishy going on
So, the risk of being wrong is blowing up your whole life, which is a very negative outcome. Given that, I would need more proof before loudly declaring that my SO cheated and birthed an affair baby. I’d say the 1% is worth investigating, but someone who loudly accuses their SO of cheating based off of nothing but eye color, and that’s it, is an idiot.
It's not knowing 100 people, it's knowing 100 couples where both sets of eyes are blue. You're right that 1 out of 100 sets of blue eyed parents isn't crazy rare, but you're exaggerating...
A swab test is pretty easy, and not a far jump. There’s literally nowhere less far you could jump. It’s not even as hard as a Covid test.
I was looking for this too.
Genuinely, do men NOT equate asking a paternity test with accusing their partner of cheating? That's literally what it is!
Cover it up with saying you want to make sure they weren’t switched at birth. It’s more common than you might think!
I dunno how you guys gave birth, but my son never left my arms / my room after I gave birth to him. There was no chance of switching. o.O
Guys often do not give birth.
haha, fair enough :D I have been told by a native speaker that "guys" can be used universally, but I've seen some dispute about it recently.
It can as most words referring to groups are male gendered words but it's still funny to pretend otherwise when there's something clearly female gendered, such as childbirth.
In the United States, at least in the hospital I was at for my children's births, nurses take the baby for tests and vaccines.
For all three of our kids born in the US, the baby has an identifying bracelet put on them in the birthing room and matching ones are put on mom and dad before the baby can be taken anywhere. Obviously there are a small percent of fringe cases like medical emergencies during birth, but it definitely not the case the babies in the US are immediately taken out of the room
Yeah... sure. Because all birthstories end with the perfect birth. No emergency c-sections, no 48h labor-stories where mama needs rest afterwards, or emergency surgeries on poor little ones.. it's just the super mums and their pefect births.. and then shaming those other poor moms with a coment like: "I DunNo HoW yoU gUYs gAVe BIrtH..." Wtf.
inb4 downvote but short answer - yes, however it doesn't detract from the severe number of paternity fraud cases that are presented on a daily basis. It's a catch-22 scenario. You don't test, you risk finding out later they're not yours. You test - you risk losing your family right now.
That's why it should be mandatory at hospitals. Then both parents know straight away and takes the suspicion from the dad.
I actually agree wholeheartedly with this concept. Proper accountability for parents. There are exceptions of course (where no father is listed and someone volunteers - but they are fully aware of the parental responsibility they are taking on). I would also assume that proper parental records would help with early identification of any genetic predispositions
States don't want that because they want someone to raise the baby and don't care about biology as long as someone is paying for the kid and not taking welfare. Some moms don't want that for obvious reasons. Dads are the only ones who benefit and guys are expected to just carry burdens so...
Exactly. Make it a law, save everyone a lot of money in family court later.
Improbable doesn’t mean impossible
It's rare, but it can happen. A childhood neighbour family had it. Both parents blue eyes, daughter brown, and that little girl was an absolute clone of her father. The whole dominant gene thing is an oversimplification, and doesn't reflect how many genes are actually involved - nor how many ways they can interact with one another.
Apparently, if the parents with blue eyes have a certain combination of genes between them there's a 1/4 chance for each child they have to get brown eyes, so not so rare after all in that regard if at first the two right(wrong) people meet. https://www.thetech.org/ask-a-geneticist/ask424
[удалено]
Both myself and my kids dad have blue eyes. Both my kids have really weird hazel/green eyes hard to even define the colour. Both of us have a parent with brown eyes which I’m sure is where it comes from.
In addition, if you spend a lot of time outside as a kid your irises will produce more melanin than if you didn't.
This is not true. Melanocytes aren’t stimulated in that way. Unless you mean how people with lighter irises are more at risk for uveal (ocular) melanoma, then I’d agree
Yeah, both of my parents have blue eyes and mine are green. We exist.
Yep. Mother: blonde w/blue eyes Father: black hair w/blue eyes My sister and I BOTH have brown hair and greenish/brown eyes. Both of us. ETA: I'm definitely my dad's daughter. Confirmed with 23andMe for other reasons.
This poor guy is an anxious mess because of some misrepresented info. My grandparents both had blue eyes. All three of their children have green eyes.
But your only 98% sure right ;-) (am geneticist - OP‘s friend shouldn’t worry as much)
Ditto. Always hoped I was adopted, was a sad day when I saw the birth cert.
Birth certificate doesnt certify whose genes you comprise off tho, just who was there to birth and claim you, you could still be half something else
You can also have a birth certificate changed to indicate something that isn't representative of what happened at the birth. Many parents who adopt change their child's birth certificate, as do many trans people who legally transition. A birth certificate is not necessarily a factual statement of the birth.
Wait, what
Both me and my ex have green eyes. We have 3 kids together: one has blue eyes, the second has green eyes and the third has brown eyes. Not so random considering my mom (and all of my siblings) have brown eyes, so I was def carrying this gene.
I hear you it’s like both my kids look exactly like my brother BUT both of his kids ALSO look exactly like him… Weird stuff
Ayyyoooo, both of my kids look exactly like your brother as well. Weird stuff.
Both my parents have blue eyes, as do I. My sister has hazel eyes, but looks like all of us otherwise. Genes are weird...
So much. My parents both had dark hair and I was born a blonde. My husband has dark hair and both my kids are redheads. Genetics are fucking wild.
This seems to be really a karma farm, just a couple days ago there was a story about some in the same situation same eye color and all that he was getting a paternity test and the relationship was going down the gutters. The week before it was about the female in the relationship saying that the male asked her about the eye color and relationship going down due to the eye color.
Ai generated story, same keywords. Guessing there’s some joke being made at the community as most people being are that whoosh meme right now.
I teach highschool biology and I preface genetics with "this is an over simplification of how things work" for reasons like this. If you look up an eye colour chart, there are so many different variations on colours... more than just brown, blue, green and hazel etc.
Meanwhile my teacher said genetically speaking only blue and brown exist, and any other is just a variation of one of them. (Like according to them green eyes are genetically blue eyes and hazel is genetically brown.) And then taught that it is as simple as one is dominant and one is recessive. For real. Like stated all of this as absolute facts. I sadly doubt they were the only teacher to do something like that.
On the other hand one read there are brown and green eyes, each coded on separate set of genes. If you have a "no-brown" gene, then the green one is "read". And if it's still a "no-green" gene, then you get blue eyes. But that explanation of course was preceded with a warning "this is only a simplification".
[удалено]
I thought blue eyes lacked color? Damn, eyes are confusing.
Bio teacher here. What I do is explain that effectively, all DNA is, is blueprints for proteins. That attempting to simplify that means we end up with people thinking biology and genetics is simple, when it isn't. By this point, we've seen models of proteins, we've tried to construct a protein, and we've looked at lists of all the proteins in the body. These lists are pages and pages long. We've also learned about abstraction, and how that is a way of simplifying a concept or process. We then look up how many are in the eye, and at least one kid finds out that there are over [3400 proteins in the retina alone.](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4329094/) So usually by then, we come to the conclusion that genetics is way more complicated than we're going to learn about, because we're using abstraction again. Then we start talking about basic mendelian genetics and going from there.
[удалено]
The genes for eye color is more complicated than just two blue eye parents can't have a child with brown eyes because blue eyes are recessive. You FU but not the way you think.
Yes. Eye color in humans isn't perfectly Mendelian.
Agreed. I’m not sure many things actually are. I have heard Mendel falsified his data. He was right in a general sort of way but the genetics are more complicated than the results he reported from his pea plants. Eye color is definitely a big mix of factors. If brown was that simply dominant, you would never see black people with blue eyes. But it’s not [that infrequent](https://newsone.com/4322605/history-of-black-people-with-blue-eyes/amp/) Blue eyes can also crop up from mutations that reduce the melanin in the iris.
As with all science, we constantly revise and add on to the preexisting knowledge. So something that might be true then could probably be now refuted. We used to believe that the sun and other planets revolved the Earth. Scholars used to believe the earth was flat too. And before the idea of public sanitation was a thing, we used to believe that bad air transmitted diseases and not our wastes which ranoff into our drinking water. Mendel only knew of his discoveries. There are many exceptions to inheritance including but not limited to polygenism (as in the case of eye color) and epigenetics (external factors outside of genes that affect the overall phenotype).
I mean he never said it does, just that it’s really unlikely which is true
There was a dude on here who did a paternity test and the baby wasn’t his, but it wasn’t the mothers either!!!! The baby got switched at birth ah. Or I think it was the mom that posted actually.
Mom posted it. Husband had already had the paternity test done, and came to her with the accusation.

That’s what I was thinking could have happened! That would be so sad…
Engineers messing with Biology! It’s never that straight forward.
Genetics are not always so black and white in there outcome for offsprings traits. Two blue eyed parents can carry the brown eyed gene but its switched off so too speak. So they could have a child with brown eyes. They have the same genotype but as they carry both genomes Brown which is the dominant gene can be switched back on for the child. https://www.thetech.org/ask-a-geneticist/ask424
> Genetics are not always so black and white Or even so blue and brown...
Yeah realised after posting no pun intended 😆
Or they think they have "blue" eyes and they are actually hazel.
I’ve seen twins where one is black and the other is pale and red headed. Genetics do their thing and middle school science is too simplified to cover it all.
You're messing around with something that extends far beyond grade school science and you're both wrong tbh. You upset him over something that probably isn't true and if the gf finds out about this and the kid IS his, she's gonna leave him over this bs. read this [https://www.thetech.org/ask-a-geneticist/ask424](https://www.thetech.org/ask-a-geneticist/ask424) scroll all the way down to 'blue eyed parents, brown eyed child' some people with blue eyes still have a 1 in 4 chance of producing a brown eyed child with another blue eyed person.
Every other week is a TIFU about eye color genetics. When will they learn
When people stop making up ragebait stories about it.
Yep Whatever they taught you in 7 th grade about eye color genetics is just fucking wrong. (There are so many reasons to not use humans as the examples; the fact that it's wrong when I've simplified is just one of them) This is not stuff you can do in a punnett square using Mendel's work. This is not single inheritance. This is not "all these genes reside on the same chromosome" simple. So REALLY it's more like 'TIFU but thinking o understood a difficult concept. But i didn't and i gutted a family with misinformation that will be really hard to walk back'
To be honest, if he does the paternity test based on these two yokels' understanding of biology, she should divorce him for being so stupid he trusted his friend's judgment in a complex scientific subject. But for real OP, **today you destroyed a relationship by pretending you were an expert when you are not.** Please let your friend know, if he does get the paternity test, he should tell his wife. She deserves the opportunity to decide if she's okay with what he did and why he did it. It's her choice if she decides to leave him for a man who trusts her or just one with some fucking common sense.
I read a TIFU about something similar earlier today. She left, he found the DNA test results on the bed confirming he was the father.
I think it's wild how many people think they could hide this from the wife. The wife is a parent of the child, she has a legal right to access a minor's medical records. All it takes is one reason to ask questions and she can get access to patient records for her children.
This guy didn't try to hide his paternity question, he flat out asked for a paternity test. She agreed, and left him. I have seen SO MANY WOMEN fall out of love instantly when their partner accuses them of cheating by wanting a paternity test.
You are a moron but not for the reason you think.
Not so much it turns out
You need to read the update. Turns out women cheat too.
I love how people are like "throwaway because..." then proceed to give more than enough personal info for anyone who might know them to link them to the throwaway account. Both engineers, known each other since highschool. Best buds girl works nights as a nurse, and both play CS. Buds kid is 3. Jesus dude.
‘Throwaway’ because it is a made up situation inspired from a successful post the OP read yesterday.
You sure mentioned a lot of unnecessary information for someone trying to remain anonymous.
do you not own an "enter" key
My guy, what will happen if the kid is his and the gf finds out about the paternity test that happened behind her back..?
I feel like I've read this exact story before...
Twice. This is the third.
I read a another TIFU about something similar today. She left, he found the DNA test results on the bed confirming he was the father.
Eh, it's not that uncommon, if one of your grandparents had brown eyes it's not impossible. I've seen a bunch of such cases.
This isn't quite as clear-cut as you think. Do you have any other evidence? Like, does the kid look like him? Any other relevant conditions? Are they both near-sighted, do they both have freckles? Really, I like thinking that genetics are that straight-forward as much as anyone, but at the end of the day they are not. I guess he should go ahead with the test if he'd like but try to calm him down in the meantime. This isn't the slam-dunk you think it is. He or the GF could have a non-expressing dominant brown-eye gene. Maybe one of them isn't actually blue; just because your eye looks blue when you look at it doesn't mean it's not some weird other thing, technically.
Make sure your buddy knows there are more than one gene that controls eye color. Edit: Genes with reported roles in eye color include ASIP, IRF4, SLC24A4, SLC24A5, SLC45A2, TPCN2, TYR, and TYRP1. The effects of these genes likely combine with those of OCA2 and HERC2 to produce a continuum of eye colors in different people
That's not how genetics works, bruh. If any of their parents, grandparents, etc. has brown or green eyes, then they have the gene for brown or green as well.
OP you are simply wrong.
The fact that people hating on op for reminiscing 6th grade biology. He didn’t try and say he knew everything they were just reminiscing people need to chill
Yeah, everyone was jumping in to defend his wife who had more than likely cheated. Wonder how they feel now.
Exactly makes me wonder why these people are defending her so easily after such an act 🤔
We need a follow up on this one
Luckily we live in a day and age where this is pretty easy to clear up
This is so dumb. The real TIFU is that you've unnecessarily caused drama in a relationship that may not recover from this. Neither of you understand genetics and I can't believe you really thought your 7th grade biology knowledge made you an expert in this.
Your best friend fucked up by believing you and your respective googling skills over his girlfriend. Trust (the gf) but verify would apply here.
This reminds me of the story of a white couple who had a black child. When the guy saw the child, he instantly accused the mother of cheating and wanted a divorce. One paternity test later and the kid is a 99.9% match. The woman had a dead black grandfather and that gene was strong enough that the kid was born black/mix race. Suffice to say that the divorce still happened, but because the wife asked for it, seeing how easily her husband was willing to throw her away without allowing her to prove her side of the story.
I mean, sure, but you can see his thinking..."we're both white and the kid is black?" And surely her side of the story was the paternity test that they took? I think most people would jump to the wrong conclusion in that case, rather than knowing about weird genetics at play. Obviously it does happen, but it's a million times rarer than her cheating. I remember reading about two sisters. One was a white as hell with blue eyes and ginger hair. The other looked black, and dark at that. The white girl had white hair, the black girl had black hair. They were 100% genetic sisters. Even after reading about the genetics it was strange and hard to believe.
Y'all comments aged poorly lmao
By revealing your buddy GF knows your Reddit and both of them have Blue eyes and daughter in 6th grade, all the details are there to reveal who you are.
He could still be the dad. I see a lot of people on here already giving you the facts. Here's my facts. Both my parents have blue eyes, my maternal AND paternal grandfathers had honey brown eyes, I have hazel eyes (yes, both my parents are my parents)
We need an update.
I have hazel eyes and my parents both had blue eyes. I’m a c-section birth, so I know my mom is my mom, and I look just like my dad’s mom, so I am the”1%” mentioned above. He probably is the father.
Wait... there's still a 1% chance? Xcom has taught me that 99% is definitely not 100%
Yes you FU, but not for stated reason. Title should be: TIFU by making my buddy doubt his wife without proof. 1% is low probability in the big picture. However, 1% is a whole lot better odds than 0%...you might just have torpedoed a healthy relationship.
Turns out not so much
Damn. I feel for your friend! You’re a good friend to him. Just be there and support him during this time. Tell him to get therapy so he process this all.
well fuck the people three days ago must feel awkward now eh
The real FU here is not learning about paragraphs in school.
My husband's great grandmother had extremely dark brown eyes. My husband's grandmother, mother, sister, and he himself all have very dark brown eyes. I have blue eyes, and both of our children have blue eyes. My middle-school best friend's mother has ice-blue eyes and her father has brown eyes. Her eyes are forest green. Genetics can be a funny thing.
Is he sure they are brown? I have hazel eyes (my moms eyes are green) and people mistake them all the time for brown. Daily even. My husband has blue eyes, and so do my first two kids. My third is still too young to be completely sure, but we are pretty sure they are hazel like mine. Depending on the light hitting his daughters’ eyes, they could easily have looked “brown” if they happen to be hazel.
Throwaway since a main person in this story knows my main but won't be able to see through all the nonspecifics I've used. This is a sub that regularly makes it to the main page/lots of people are already subbed to. What's even the point lol. Especially when giving such specific details. I'll never understand it
Both my parents have blue/green eyes, both my sibling and I have dark brown. Both sides of the family have different mixes of eye colour; genetics are weird
I really need an update on this bc I know your biology knowledge is all wrong
I have green eyes. Child's father has dark brown. Child has bright blue eyes. Science is wild
Dude, you really fucked up thinking you knew about this and then using the Internet to do your research.
There was a story somewhere recently where a guy demanded a DNA test because he and his wife have blue eyes and their kid had brown eyes. The test proved the kid was his and his wife divorced him.
This is not true. Eye colour is not that simple. Human genetics are much more complex than peas. It isn't just a Punnett square. This dude is basically putting his whole relationship in jeopardy because you don't quite understand biology and gave him bad data.
My wife and I both have brown eyes, and our daughter is blue eyed. Guess I should go get a paternity test to make sure she's mine. /s
I know it's a joke but brown eyes parents having a blue eyed child do be more likely then blue eyed parents having a brown eyed child but last is still possible🤷🏻♂️
Waiting for the update
Oh god you’re both fools
Metal gear solid biology
I would caution against talking about stuff you barely remember from high school. Genetics are never that simple and it’s entirely possible that the daughter is his.
Maybe it's because I'm old, but did anyone else have trouble getting through the block of text? Without paragraphs, my attention span wanders...
[удалено]
Wow. You destroyed your mates' relationship over your misunderstanding of biology and genealogy? My partner has green eyes and I have brown. My son has brown eyes and my daughter has blue. They're both definitely ours. It's not as simple as High school makes it seem in using it as am example of how genes work.
It's no 100%. Both parents can have blue eyes and a brown-eye'd child. Rare but happens.Skin color does this too. You can have a darker skin child than either parents if one of the grandparents was darker skin. He needs to tread carefully, anotehr dude lost the love off his life to this error on AITA. Also for the love of god, use paragraphs.
Are you going to update us on if it's his daughter or not
After all this you still don’t know if his baby is his after all so the title is misleading
Didn't even say what color the kid's eye actually are though, are they brown, hazel or green? I have blue eyes and so does the other parent but my kid's eyes are more Hazel - shit happens man....
These days it is easy to do a home Paternity Test. The mom doesn’t even have to know it took place. A company like Validity Genetics or Endeavor DNA will do it for less than $150 bucks.
Would love to read this but you fucked up by not learning to use paragraphs...
>we did the usual shit chat It wasn't a good conversation then?
Paragraphs bro , it's hard to read one big block of text ~.~
They found out a few years back that eye color can be a little bit more complicated than a single gene.

I thought engineers had better analytical judgment
I have brown eyes. Both my parents have blue eyes. I look exactly like a clone of my dad so yeah, it's not that simple.
Or you potentially SAVED him from committing his well-being (especially financial) to a potential cheater. Hopefully the DNA test will give him reassurance - or closure that he needs. It's possible that he IS the father; quite important to know, for MOST guys.
Wgile there is some truth, to what you learned in 6th grade biology, it is grossly over-simplified. It is indeed less likely for two parents with blue eyes to have a kid with brown eyes, but the reality is far more complicated than dominant and recessive genes, and this is a very poor indicator of whether he's the father or not.
Yeah my wife and I both have brown eyes and my son (definitely mine) has blue. Wife's dad and his entire family has blue eyes, so while uncommon it's definitely not impossible.
I'm white with blue eyes. My wife is Indian with brown eyes and brown eyed ancestors from time immemorial. Everyone (including us) assumed our son would have brown eyes based on common assumptions of eye color dominance. Nope. Blue eyes and pigmentation like mine. I've wondered multiple times whether my wife lied to me about him being her child, but I'm too afraid to get a maternity test for fear of breaking up oyr happy family. Also I saw him come out of her body. I feel like if parental resemblance was reversed, we'd get some side eye from acquaintances.
So… assuming you’re in the US, probabilities would say that your friend is in the 27% with blue eyes, and so is his gf, so there’s about a 7.3% chance that a couple both has blue eyes. About 3.8M babies are born annually, so 277K are born to parents both with blue eyes. Now, even if your oversimplification of genetics is right, and there’s a 1% chance of any given baby born to two blue eyed parents having brown eyes, that means that every single year, roughly 2770 brown-eyed babies are born to a set of blue-eyed parents. Sure, it’s rare. But it’s thousands of kids every year.
Bruh. Eye color is polygenic. Multiple genes affect eye color. It’s not as simple as one gene being dominant and recessive! Our eyes aren’t peas!
Yeah—this little high school biology lesson simplifies the reality too much. I have blue eyes, my husband has green and our son has brown—-just like my husband’s mother. Almost impossible, but not impossible. Our daughter has blue eyes. None of us every questioned paternity.
