Intelligence really does come from moms, according to science

Mothers of the world, rejoice! Science has found more reasons for you to feel more proud of your kid’s smarts. According to psychologist Jennifer Suarez of Psychology Spot, mothers are responsible for transmitting the intelligence gene.

The intelligence gene is found in the X chromosome

Several studies, including one done recently at the University of Ulm in Germany, found that intelligence genes are located on the chromosome X. Since women carry two of those, that means children are more likely to get their intelligence from their moms. “It’s no coincidence that the intellectual disability is 30% more common in males,” Suarez went on.

A study by the Medical Research Council Social and Public Health Sciences Unit in Glasgow, Scotland also found that the best predictor of intelligence was the mother’s IQ. “The ratio of young people’s intelligence varied only an average of 15 points from that of their mothers,” Suarez reported.
