Do Kids Inherit Intelligence From Mothers?

All these variants function together in different ways to form what we view as intelligence. Also, know that each of these heredity fragments that contribute to intelligence is influenced by a range of environmental factors – both in its immediate molecular world and inputs to the whole organism, that will influence function. 

This influence continues after birth as an ongoing mutual interplay of gene variants and environment. It’s like several layers of interacting pieces. 

Therefore, you don’t just inherit intelligence from your mother. It’s not just the X chromosome. And it’s also not just about genes. 

Inheriting the X chromosome from the mother is just not enough to make you intelligent. Because intelligence is not just about solving complex problems. Rational thinking function is also affected by emotions and intuitions, which are also contributed by fathers. So, dads are equally responsible to bring smarts to the world. Even if a child has a high IQ, it must be nourished throughout life with new challenges. Otherwise, intelligence will disperse.

In earlier research by Africa Check, professor of metabolic medicine Fredrik Karpe told that kids Intelligence is also determined by economic, cultural, and social environmental factors.

What is all the buzz about conditioned genes and intelligence?

Some online blogs and news stories have also mentioned conditioned genes that are activated only when inherited from the mother and that is vital for embryo development. 

According to researchers, “conditioned” genes refer to gene sequences that are tagged as being of maternal origin. However, we also require complementary gene sequences of paternal origin for the entire process to work out. 

Some articles that have spread the news that intelligence is inherited from the mother have also highlighted the results (given below) of a 1996 paper to support their claims – 

Researchers found that embryos survived when normal embryonic cells were maintained. When they manipulated the rest, they created several genetically modified laboratory mice that did not develop in the same way. Mice that received an extra dose of maternal genes developed larger heads and brains, but smaller bodies. By contrast, mice that received an additional dose of paternal genes had smaller brains, but larger bodies.

But the fact is this experiment involved mouse embryos that were a mix of cells, while some carried double maternal genomes, some carried double paternal genomes. Some parts of the mouse brain that developed carried far more than the other whereas other parts of the brain showed a reverse pattern.

Barry E. Keverne, the senior author of the 1996 paper reported in 2013 that some of the findings may have been the result of a “failure of these (double paternal) cells to thrive and survive when they reach the developing cortex.”

Is it true that paternal genes are not found in the brain regions responsible for intelligence?

A lot of people in online forums argue that the mother’s genes go directly to the cerebral cortex, while paternal genes go to the limbic system. And the cerebral cortex is the region where humans develop advanced cognitive skills like language, thought, intelligence, creativity like painting. 

Well, referring to the 1996 study involving mice, yes it is true double-paternal genes are excluded from the brain regions responsible for intelligence. But, it is also not the right thing to say that our cerebral cortex excises with surgical precision those parts of the cellular genome that are paternally inherited.

Most of the old papers concerning embryo development are 20-30 years old and primarily deal with the discovery that an appropriate embryo development requires both a paternal and a maternal genome and in the absence of these complementary genomes, development fails. Also, when you use your brain you use both cerebral cortex and limbic system functions.

Hi there! I'm just a normal person enjoying the process of life. Practicing Buddhism, I believe in the law of cause and effect. Reading and writing is always a pleasure. I enjoy researching on a range of subjects – science, psychology, and technology. Nothing can satiate my soul than good music, horror movies, psycho-thriller, and crime stuff. I enjoy photography, music and watching comedy videos. Talking to people, learning new experiences, sharing my knowledge through blogs, motivating others are things that I always look forward to.View Author posts
