Report: children inherit their intelligence from their moms

Report: children inherit their intelligence from their moms

(WVUE) - Scientists at the University of Washington found intelligence genes are carried on the X chromosome and women are more likely to pass them on since they have two, compared to the one men have.

In an article published in Yahoo News, researchers in Glasgow found advanced cognitive functions children inherit from their father may automatically deactivate, and thus have no impact on their children.
The article says during lab tests, mice that were given extra maternal genes developed larger heads and brains, but had smaller bodies. Those mice given extra paternal genes had smaller brains and larger bodies.

University of Washington researchers were cited as saying they believe children who are supported emotionally have higher growth in the parts of their brain associated with memory, learning and stress response.

"The scientists extended their study to humans and after interviewing 12,685 people between the ages of 14 and 22 every year from 1994, concluded that that the best predictor of intelligence was the IQ of the mother," the Yahoo article states.

Scientists say while genetics play a role in intelligence, environmental factors also can have an impact.
