As you may have guessed I don‘t have a doctorate in genetics, just like you, I assume.
I don‘t get to determine biological definitions, but the definition of a biological sex, if such a thing exists, is still heavily debated in science. Therefore a consensus couldn‘t be reached so far. I just argued for the definition, that sounds the most logical to me. If you have other definitions or models I am open always open to learn.
Thanks for the sources.
The first article doesn‘t invalidate my thesis. It explains the difference between sex and gender.
The second article argues against the sex binary, which I never defended. I view „male“ and „female“ (in the context of the biological sex) as terms for a combination of chromosomes. The article still was absolutely worth reading, thanks.
The third article actually lists a bunch of stuff I didn‘t know about. I‘m going to look into that.
