I was unaware that an X chromosome could mutate into a Y over the course of a lifetime. Do we know what causes that?

They are not saying that the X chromosome mutates to Y, but rather saying that XY doesn’t define the sex. For example, some people with XY are born with female genitalia and look female their whole lives. Sometimes they don’t find out they are XY until trying to have kids and are unable to. It isn’t like the X changes to Y over time that isn’t possible.

It’s weird how your first thought is “the PhD is wrong” and not “I must have misunderstood something” .

There was a reason I made that comment

I think you may have misread. The PHD isn’t saying that XY becomes XX, they are saying, genetically, a person carrying XY can be a cis woman. Biologically, XY doesn’t determine the sex.

Thank you for clarifying

I honestly don’t understand. What does define the sex biologically? The genitalia, then? I always understood positions like William’s like “XY is the biologically male sex by definition, if the human develops female genitalia and feels like a woman they were biologically speaking still intended to be a man.” I don’t understand what else there could be on an elemental level to biologically deternine the sex.
