āIn the XY sex-determination system, the female-provided ovum contributes an X chromosome and the male-provided sperm contributes either an X chromosome or a Y chromosome, resulting in female (XX) or male (XY) offspring, respectively. Hormone levels in the male parent affect the sex ratio of sperm in humans.āĀ Now no, chromosomes donāt entirely determine gender, but they do however, determine sex. And sex is very closely related to gender. Thatās just a fact. Now you can be born a boy, and think you are a girl. The issue with that is you still have a dick. So like it or not, you are still a boy. And the transition surgery does not count as you still will not be a woman as your genitals were built of XY chromosomes. Same goes for girls to boys.The surgery does not change the fact that your genitals are still made of XX chromosomes. So by there only being a penis and vagina, there are only two sexes, which means there are only two genders to go with the two sexes. Non-binary does not exist.Ā Abimegender,Ā Adamasgender, Aerogender, Aesthetigender,Ā videgender, Affectugender, Agendegender, Agenderflux, etc. do not exist. they are all made up. And the fact that you believe you are a gender different than the one you were born as is a mental disorder called Gender Dysphoria. Mental disorders can cause people to do rash and stupid things. This disorder is one of them.
