Just look at this. I take a dude and a chick, I combine them together and let the genetics work it out.

What's between the legs of the result? A fucking vagina and nothing else. Explain this shit.

If the girl always wins, how come the male birthrate outnumbers the female slightly?

Mortality rates among male babies is higher than females though. I think in the end it comes out nearly 50:50.

If I remember high school bio in each cell only one X or the other is expressed the other remains dormant. So XXX would be a fairly normal but infertile girl and XXY or XXXY is a guy but often not very masculine. The XXY is called Klinefelter syndrome. I Have also herd of XXX or XXXX+ referred to as super feminine but that term is kind of funny and probably not politically correct because they are infertile.

So op is right the shit makes no sense if one was guy and the other a girl, but thats not the only thing wrong and honestly this does not stand out on the hard to buy porn concepts list.
