As in X chromasome linked, like colour blindness that has nothing to do with reasoning.

Colour blindness is in the retina not the brain so of course it has nothing to do with reasoning...

Although I do see what you're saying, I suppose. The abnormality that causes colour blindness is linked to the X chromosome but there is no structural difference between "normal" male and female eyes, and the same might be true of abnormalities in the brain where there are large statistical differences between men and women.
