When it comes to IQ, new research documented by Psychology Spot says we really do ‘get it from our mamas’. The findings say that people are born with conditioned genes that work differently depending on if they’re from your mother or father — and when it comes to your intelligence, those genes are from your mother.
Although many people previously believed your intelligence comes from the father and mother, that is not the case, the study says.
Intelligence genes are located on chromosome X and since women carry two, that means children are twice as likely to get their intelligence from mum.
Even if your father passes off a few of his intelligence genes to you, chances are they won’t have an impact on your brain since they only work if they come from your mother.
“If that same gene is inherited from the father, it is deactivated,” reports the study in Psychology Spot. “Obviously, other genes work the opposite, are activated only if they come from the father”.
On the other hand, the report has been rubbished by other scientists who claim it to be false. Science contributor at Forbes.com, Emily Willingham said: “Whatever is on the X can pass from mother to child or father to (usually) daughter, but the two X chromosomes the mother has aren’t the same, and don’t at all automatically double the odds of inheriting a specific variant”.
Nevertheless, the Medical Research Council Social and Public Health Sciences Unit in the United States carried out a study on mothers back in 1994, and interviewed 12,686 young people between the ages of 14 and 22. Their questions focused on the children’s IQ, race, education and socioeconomic status. The best predictor of intelligence? The IQ of their mother.
