If you have one or more "Y" chromosomes, then you are a biological male.
If you have no "Y" chromosomes, then you are a biological female.
There may be other combinations that I am not aware of, but it is the presence or absence of a "Y" chromosome that determines whether you are male or female.
However, these syndromes are extremely rare; and those who were born with them generally have physical deformities. Therefore, if you were born a healthy male, you can safely assume that you have an XY chromosome pair; and if you were born a healthy female, then you can safely assume that you have an XX chromosome pair.
I realize that there are transsexual and intersexual people who feel that they were born the "wrong" gender.
I appreciate your perspective, but that is a psychological issue, not a genetics issue.
Furthermore, I understand that transsexual and intersexual people disagree with all this for political reasons. Unfortunately for you, these are scientific facts.
If you don't like it, then flame God, not me.
I respect your right to be gay, so please respect my right to be straight.
