| Comment | Sex is actually less binary than you'd think, depending on who you ask and what you're referring to.
Does the person have a penis or a vulva? That's almost always binary, with a few rare exceptions.
Does the person have high testosterone, excessive facial hair growth, etc ... that's a soupy mix of genetic markers, including some pre and some post natal that don't even fully develop until your teens.
The correlation between the markers and the observed genitalia map out to two normal distributions - meaning a baby born with a penis is as likely to grow a beard as you are to score 50% in a class test. Maybe, maybe not. |
