Can a man and a woman both have XX chromosomes?

Question

How do the Sry and Sox 9 genes work in the determination of man or woman?

Answer 1

The genetically correct male is XY and the female is XX
in order for a male to have two X, then he must has Kleinfelters syndrome which makes XXY
A female can have Turners syndrome which is the appearance of only one X
only certain SOX genes are correlated to sex determination
the sry protein is the sex determining gene in mamals

Answer 2

What the whole "x" and "y" chromosomes are, are the 23rd pair of chromosomes that a human being has. Women have "XX" and men have "Xx" - but the little "x" looked like a "y", hence "XY" as we now know it. It's been a while since I've had bio, but if my memory serves, it is sometimes possible for a man to have an "XXY" in which case he is sterile, but still have the physical attributes of a male. I'm not quite sure if that really helps at all...but unfortunately, it's been too many years since I've had bio to answer the question fully, but I thought that that was kind of neat that some guys can be a little more feminine than others.

Answer 3

Everybody has at least one X chromosome, women XX and men XY. It is possible however for a male to have 2 X chromosomes if he is a Kleinfelder male and an XXY chromosome triplet. These men usually seem to be rather feminine and often require medication and possibly surgery to appear more masculine.
