Throughout history, men have often been depicted as rational, logical, and intelligent thinkers.
A study has shown that ‘smart genes’ can only be inherited from the mother – not from both parents as previously thought.
A new study has proven that our intelligence comes from the female X-chromosome. Intelligence is known to be inheritable, with genes traditionally thought to be inherited from both parents.
Psychology Spot explains that children inherit intelligence from their mothers because the intelligence gene is located in the X-chromosome.
“Interestingly, some of these genes only function when inherited from the mother. If the same gene comes from the father, it is deactivated. On the other hand, other genes work differently, being activated only when inherited from the father,” stated the study.
Researchers explain that genes operate differently depending on their origin. Some genes are gender-specific in their activation. Consequently, even if a child has an intelligent father, the father’s intelligence genes are overruled by the mother’s chromosomes.
Moreover, while genes play a vital role in intelligence, they are not the sole determinants. Studies suggest that only 40 to 60 percent of intelligence is hereditary.
The remaining portion is influenced by the child’s upbringing, brain stimulation, and individual traits.
