In the case of your intelligence, “I got it from my mama” couldn’t be more accurate. New research featured in Psychology Spot says 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 mama.
Even though people used to believe your smarts were from your father and mother, that’s not the case. You see, intelligence genes are located on chromosome X and since women carry two, that means children are twice as likely to get their intelligence from mom.
And 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.”
