Doubt you ever took Bio 101 at the college level. (Actually this is taught at the high school level) If you had, and paid attention, you'd know that not everyone is XX or XY. Genetecists also know, that even if, say XY, a screwup in utero with the amount of testosterone produced and released, can make someone who is XY, functionally female due to hormones.   The X and Y genes instruct millions of other genes how to perform.  Lots of ways that can go wrong.  Did you even know that there are XYs born without a penis. Most time everything works according to "plan", but not always.  (This is a very dumbed-down explanation for you idiots living in the past.)
I love when you MAGAphants try to act smart, and then continue to look like dumb lapdogs.  What a moron.  No fair crying about being called a name.  When you act like an uneducated, stupid, MAGAphant, moron, you're going to get called names.
