I actually have XYY. I discovered it bc I participated in a test for genealogy of known Cohens. Both are the same and both my fathers.
They used to think XYY were prone to being criminals and thugs and less intelligent. Not true. I went to MIT and not exactly a lifetime criminal, unless you count speeding.
What is true is male secondary sex traits are slightly exaggerated. So I am a bit taller than I should be, am rather hirsute, have a pronounced chin, and always gained muscle very easily from exercise. Tend to smell rather, dank of I don’t shower a lot.
How’d you come out vis a vis the Cohens study?
Who knew? Screen names are more literal than people might ever suspect! :)
I figured that this was a description of Esau:
The forewings of this species are reddish brown with distinctive patterning towards the base; a black mark resembling the Hebrew letter nun (נ) with a pale cream-coloured area adjacent to this mark. The hindwings are cream coloured.
The question that this begs is how does it affect fertility?
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...................
