Extra Chromosomes and IQ

[PvtJoker]

Just reading on Wikipedia that the average IQ of women with XXX Trisomy (extra female chromosome) is around 85-90, while the average IQ of men with XYY Trisomy (extra male chromosome) is around 105.

Figured that would stir a lively Friday discussion.

You back again aren't you?

Don't you ever give up and move forward to repair yourself?

You must have created like 3 accounts per day in August.

What is the IQ difference between XX females and XY males?

I've worked with a couple men with an extra chromosomes. They were on the lower end of iq and had behavioral issues.

Interesting, I have encountered some that I suspect are missing a few chromosomes. The could be that missing link between apes or proof that Neanderthals didn't disappear but just interbred with homosapiens (women attracted to the big dumb guy). I admit the heavy eyebrows hold the MAGA hat firmly in place.

Ok, so the next question that should be asked is how were the sample populations selected. The reason I say that is many years ago there were some studies that linked extra Y chromosomes in males with more agressive behaviour. However, there apparently was a problem with how they selected the subjects in the study. I think it had to do with choosing male subjects from prison populations.

The answers are in the refs on the wiki page.
