Of course you are aware that around the country there are legislative efforts to force transgender people to use the bathroom and locker rooms reserved for the sex we were assigned at birth. In some places, it is phrased rather as requiring those facilities to be segregated by chromosomes.
Awkward, that. As a society, we have never determined assignment of sex at birth by a test of chromosomes. I'm 68 years old and, as far as I know, I have never had my chromosomes tested. Ever.
I find it stranger still that the forces calling for this anti-transgender discrimination have such little regard for science in general. These are people who believe the universe was created between 6000 and 7000 years ago, that a woman was created from the rib of a man, and that Jesus rode to Sunday School on the back of a dinosaur.
