According to recent findings published in Psychology Today, it appears that children derive a significant portion of their intelligence from their mothers. In fact, some studies indicate that as much as 77% of intelligence may be inherited through maternal genes. This stems from research suggesting that the genes associated with intelligence are predominantly located on the X chromosome. Given that women possess two X chromosomes while men have only one, it stands to reason that mothers are more likely to pass on cognitive aptitudes to their children.
On the other hand, the Y chromosome is linked to physical traits, implying that fathers might be more responsible for their children’s physical attributes. This might explain why little Liam struggles in both math and gym class—just kidding, it’s primarily gym class.
Interestingly, while the study utilized mice in its analysis—showing that those with enhanced X chromosomes developed larger brains—it’s crucial to note that these results may not entirely translate to humans. Therefore, there remains a glimmer of hope for fathers like myself that we too contribute to our children’s academic achievements.
Currently, my kids are still in the “adorably clueless” phase, which makes it easy to attribute their quirks to my wife’s influence. After all, my five-year-old’s fear of tissues is clearly a maternal legacy. Yet, it is evident to anyone who meets them that they inherited their stunning good looks from me.
Yesterday marked my ninth wedding anniversary, and I’ve long accepted that my wife holds the intellectual edge in our relationship. This realization has led me to humorously conclude that perhaps my perception of her being right all the time stems from her superior genetic endowment.
In light of this revelation, men might find themselves thanking their mothers for their inherited intelligence, while also holding women accountable for any of our blunders. If our cognitive capabilities are indeed linked to the brilliance of our mothers, it’s not entirely our fault when we can’t locate something we just asked for—even if it’s right in front of us.
It’s worth remembering that the study suggests only 40-60% of intelligence is hereditary, with some of that undoubtedly coming from fathers as well. The remainder is influenced by environmental factors, personal experiences, and stimulation. Given that my six-year-old is already displaying a sarcastic wit reminiscent of his dad, I suspect I have a significant role in that development.

In conclusion, while the notion that children inherit intelligence primarily from their mothers is supported by science, both parents contribute to their offspring’s development in significant ways.
