As many as one in 500 men may carry an extra sex chromosome — either an X or a Y — but very few of them likely know about it...
The research, published June 9 in the journal Genetics in Medicine(opens in new tab), included data from more than 207,000 men who provided information to the U.K. Biobank, a repository of genetic and health data from half a million U.K.-based participants. Typically, males carry one X- and one Y-shaped sex chromosome in each of their cells, but among the study participants, there were 213 men who carried an extra X chromosome and 143 that had an extra Y.
Very few of these men either reported being diagnosed with a chromosomal abnormality or had such an abnormality noted in their medical records: Of the XXY men, only 23% had a known diagnosis, and just 0.7% of the XYY men had a diagnosis. (The potential symptoms of having an extra Y chromosome can be very subtle, which may somewhat explain the difference in diagnosis rates, according to the Genetic and Rare Diseases Information Center(opens in new tab).)...
Previous estimates suggested that roughly 100 to 200 men out of every 100,000 are XXY, according to the National Human Genome Research Institute(opens in new tab), and an estimated 18 to 100 out of every 100,000 were thought to be XYY, the authors noted in their report.
In all, about 0.17% of the study participants had an extra sex chromosome, or about one in 580. However, the rate observed in the study might be slightly lower than that among the general population, the study authors noted in their report. That’s because U.K. Biobank volunteers tend to be healthier than the general population and have a lower-than-average incidence of genetic conditions.

No doubt there’ll be an mRNA gene therapy to fix that!
Sounds like a guy I knew in the Marines, long ago.
He was so hairy, he could walk down the street naked and people would think he was wearing a gorilla or Big Foot costume...................
I got a couple bro-in-laws like that.
We used to watch it at lunch time in the Marines..............
According to the Old Testament, Esau, son of Isaac and brother to Jacob/Israel, was like that, with red hair.
He must have looked like an orangutan..............
I think the only redhead besides Esau mentioned in the OT is King David.
Cool!
Add Solomon as a redhead. Both he and David are described as being handsome.
I am ‘preprogrammed’ to like redheads. My mother, grandmother and a sister were all redheads...............
Greatest game show ever!
I’m not that hairy! LOL. Also black hair.
Apparently when you have XYY you have double the androgen receptors in muscle, various bones, and, yes, hair.
So whatever androgens (eg testosterone) floating around had almost 2X effect. I easily could have been a bodybuilder, although that would require a lot of shaving.
