  • Is he mixing up people with 3 gonosomes?

    Because these are not too rare. It’s one of the more frequent mutations.

    But even a person with XXY is a male. Since the male gonosome is considered as a mutation of an X chromosome. Somewhere in the evolution of mammals and other vertebrates (or most likely much earlier) something messed up and created the Y chromosome from an X chromosome. That’s why genetic diseases are usually more frequent in males, since one branch of the X chromosome does not have some backup. It’s simply missing.

    So whenever a person has one Y chromosome. It is considered male. The lack of a Y chromosome is considered a female.

    This can also be seen in people with genetic disorders, such as three gonosomes. XXX is a female XYY is a male XXY is also a male.

    And to everyone’s information: I am for Germany and we do not have two words for sex and gender.

    I don’t understand what you English speakers are up to.
