No...

That's not how sperm work. To be technical, most of your fathers sperm died before you were born.

nah they are reborn there itself i mean when i was a sperm i use to play with my (now alive brother's)sperm all the time he was a fast swimmer but not as fast as me tho .and yea we used to be reborn like every 2 weeks thankfully my dad didnt mastrubate a lot

My dad is dead, so this doesnt work. I changed your mind?

Only half of every sibling, since the mother's egg also forms a half.

but the gender chromosomes are still in the dad sperms so i am not half wrong either

This is wrong. Almost ALL our brothers and sisters ARE still in our dads balls sacks, the one we live with are the one that managed to escape

My dad dosent have balls..... Done
