Numerous studies on twins suggest that between 40 and 80 percent of the variance in IQ is linked to genetics, suggesting that genetics may play a larger role than environmental factors in determining an individual’s IQ.

Does IQ increase with age?

Age. IQ can change to some degree over the course of childhood. In one longitudinal study, the mean IQ scores of tests at ages 17 and 18 were correlated at r=0.86 with the mean scores of tests at ages five, six, and seven and at r=0.96 with the mean scores of tests at ages 11, 12, and 13.

Does intelligence come from Mom or Dad?

children are more likely to inherit intelligence from their mothers because intelligence genes are located on the X chromosomes (and mothers have two). Mothers do tend to have two X chromosomes, but they aren’t identical chromosomes, and of course, they got one of them from their fathers.
