That seems like it introduces more problems than it solves; genetic essentialism as a solution to debates about gender tends to be an approach that nobody agrees with. Now you still have the same concerns about people using hormones, plus: - intersex people whose phenotype and genotype don’t match (putting them in the “wrong” category) - chimeric people who belong in different categories depending on which part of their body you sample - probably other edge cases I’m not thinking of. If your goal is just to put people into categories, it’s probably a lot less controversial to split them based on if their earlobe is attached and whether they can curl their tongue.
