Yes, there can be an XX male...the findings resembling those of Klinefelter Syndrome. Affected individuals differ from typical
Klinefelter Syndrome males only in that the average height is less than that of normal males. The majority of XX males whose
DNA is probed with Y-chromosome DNA fragments containing the SRY gene are positive for Y-related DNA; thus, an X-Y
interchange appears to be the common cause of this disorder. The management of this chromosomal disorder is similiar to that
of Klinefelter Syndrome. The incidence of a male being born with two XX chromosomes is approximately one in 20,000 to
24,000 male births
This is true...I knew one. he found out he was XX when he had six daughters and was wanting a son. He was a biology teacher so he suspected something.
I don't know why some teachers mention these things to their students. He didn't seem to be joking.
