According to this paper: Intelligence and the X chromosome by Gillian Turner, published by The Lancet (a highly regarded medical journal) in 1996, the X chromosome is dominantly responsible for coding "intelligence" and "intellectual function". Since a son inherits the X chromosome only from his mother, supposedly his intelligence is dominated by his mother's genes. At the closing paragraph the paper boldly claims (I added the bold and italic for emphasis):
In day-to-day practical evolutionary terms for our new millennium the male needs to remember that his primitive urges in mate selection are coded in his genome, and that they target current ideals of sexual attractiveness and youth. His frontal cortex should interpose reminding him that his sons’ intelligence, if that is important to him, is solely dependent on his partner, and that is mirrored in both her parents.
I am naturally skeptical of such sweeping claims. Has there been a follow up research to confirm, reject, or qualify this claim? (it's been almost 2 decades since the original paper) Is this conclusion commonly accepted by biologists?
A quick search found that this claim is repeated in the media and people's blogs, for example:
Intelligent men owe their brains to their mothers, according to research published today in The Lancet. ... [Professor Gillian Turner] concludes that if a man wants smart sons his best bet is to marry a smart woman.
Sorry, Dad. You may be responsible for your son's big nose, but all the credit for the kid's genius goes to Mom... Boys inherit their intelligence from their mothers, according to Gillian Turner, an Australian geneticist.
