It is a general belief that a person's intelligence is determined by both nature and nurture.
I can find a study by Turner 1996 ( in fact, this is the motivation of this question), which makes the claim that since several genes which determine intelligence appear to be located on the X chromosome, the one men inherit from their mothers, and since a man only has one X chromosome inherited from his mother, so that's why mom's intelligence is very important to her sons, even more so than the father's!
Thus, my question is, do the mother's genes determine the sons' inherited intelligence more than the father's, as claimed by the above paper? In other words, a man inherits less intelligence from his father than from his mother? Note that I don't discount the possibility that the father could have helped to raise his son's intelligence by actively nurturing him in the correct way, just that as far as the "intellect genes" ( if there are such things) are concerned, the father plays less role than the mom.
A similar question is asked at Skeptic.SE, but it is geared more towards the contribution of mom's genes against all factors that account for son's intelligence, nurture and nature. My question is focused exclusively on the contribution of mom's genes vs. dad's.
Any new research on this front?
