T or F? There is only xx and xy
-
Is that science or not?
-
XX and XY are not the only possibilities.
XYY and XXY also exist.
None of them affect the sex of the person.
XYY Syndrome causes exaggerated "maleness", such as excessive acne, being taller than normal. Basically, all of the bad things males experience in puberty are exaggerated but return to normal after puberty.
XXY is Klinefelter Syndrome, which only causes gender development problems during puberty. It also causes brain development issues, but this isn't a sex/gender issue.

@raphjd And there's only about ten people in the world tops I bet that have either of those.

They are a lot more common than you think.
Most people never know they have it because their condition isn't bad enough to see a doctor or the doctor doesn't think to do a chromosome test.
I mean, who is gonna have a chromosome test because they have severe acne and are taller than average during puberty?
