For a lot of families who have kids, one topic is common, and that is who did the children inherit their intelligence from? Even if you are not a parent, surely you have discussed this topic with friends of yours who are parents.
This is a hotly-debated topic. Dads and moms like to joke that the positive characteristics their kids have come from them, regardless of whether it is musical talent, smarts, sports skills, good looks or different abilities.
However, you should know that there is a reason why children inherit their smarts from their mothers. So, dads sorry for this one. Here we go.
Different studies show that the X chromosome is the one that is responsible when it comes to carrying intelligence.
Now that you know this, you should also know that men have only one (XY) and on the other hand women have 2 (XX).
Therefore, women are twice as likely to pass down intelligence to their kids in comparison to dads.
Of course, this doesn’t mean that men cannot pass down intelligence. But, one thing is certain many mothers will have the final word in this argument.
This theory is proven with different studies.
According to one study, the IQ of most kids is similar to the one of their mothers. What researchers did is that they interviewed children every year from 14 to 22 years old.
The took into consideration different factors such as socioeconomic status and education. The researchers discovered that the best predictor of IQ was the kids’ mothers and it was only around 15 points different.
However, you should know that not all scientists agree with this. They believe genetics isn’t the only factor when it comes to determining the intelligence of kids.
Some believe that only from 40 to 60 percent of intelligence is hereditary and the rest comes from the environment.
Therefore, mothers and dads, and parents, in general, both have a vital role when it comes to the intellectual and emotional development of their children by playing, teaching them skills and building confidence.
