NSX-R
Master Don Juan
I wasn't sure which one was which and after i checked the interwebs for the answer i couldn't edit it anymore. Thanks for correcting me.Sigh. The Y chromosome is the male chromosome. The X is female.
Men are XY
Women are XX.
Why do we have 2? We get one from each parent. Who determines sex of the children? The father does.
At least get the basic biology correct. Some poor dude might believe you. All humans have X chromosomes. Only males have Y (unless we get into abnormal disorders which I will not include here.). So if X chromosomes have damage or are shrinking or something that affects all people.
I know it does affect all people i didn't said the opposite .
