The question is why it is the case that after meiosis you have 50% X and 50% Y? Definition of meiosis is that a sex cell splits so the 26 chromosomes in a sex cell are 25 and then the X or Y. A man has 100% XYs. Thus, after meiosis, the XYs become Xs and Ys. If there are 100 pre-meiosis cells, there are 100 Xs and 100 Ys. After meiosis, there are 100 Xs and 100 Ys in separate sex cells. Thus, 50% of sperm are X and 50% are Y.
Holy fucking shit, I learned that in 7th grade science class. God ddammit and I went to Texas public school. And I've never had biology since then. Holy fucking shit no wonder scientists look down on everyone.
