Maybe this won’t go well with all the fathers out there, but, according to the latest genetic studies, kids inherit their intelligence from the X chromosome, which is the feminine gene. This chromosome contains thousands of genes, many of which have a direct impact on cognition.
Up until a few years ago, the scientific community believed that both parents have an equal impact on their children’s intelligence. But, according to this latest research, mothers have a far greater effect on their offspring’s cognitive abilities than fathers.
Let’s not get ahead of ourselves, as we must admit that these findings are rather controversial. We need further research to be able to reach definitive conclusions but it’s still interesting to debate on the latest news from the genetics field. If anything, they’re fascinatingly interesting and rather revolutionary.
What’s the role of the different chromosomes?
When it comes to genetics, many people haven’t got the faintest idea about how it works. That’s why before we get into the specifics of the research let’s review some of the most important things about our genetic code:
- A chromosome is the carrier of our genetic information and it’s a thread made of protein and nucleic acids.
- Every cell in our body carries one pair of chromosomes.
- Women have XX chromosomes while men have XY chromosomes.
What are conditioned genes?
Conditioned genes are the gender specific genes which, as a rule of thumb, have their properties activated or deactivated based on the specific designation and the genetic properties they influence.
These genes have a sort of ‘tagging’ system which is consisted of biochemical material and allows for 2 very important things: to trace the gene’s origin and to determine if it’s activated or deactivated in one’s body. The activated genes have a direct influence on one’s genetic progress while the deactivated genes have none.
Furthermore, if one’s characteristics are mostly influenced by their mother, their father’s genes get deactivated and vice versa.
What the study discovered?
As we already mentioned, the study discovered that our intelligence is mostly influenced by the X chromosome. It was theorized that women have a greater influence on cognition as they have two X chromosomes, while men have just one. But, there’s a lot more to this than just the number of chromosomes.
Now we’ll mention conditioned genes again, as they play an important part in this research. It’s believed that intelligence is a highly conditioned genes that we inherit directly from our maternal side.
The researchers in this study experimented with GM mice to prove their theory and were able to discover that the embryos they injected with mostly maternal genes had a much larger brain and cranium but a smaller body. The other embryos, who were injected with mostly paternal genes had a smaller brain and cranium, but a larger body.
Moreover, the researchers reached some other interesting conclusions as well, aside from the size of the embryos brain and body. They identified the 6 brain areas which contained just paternal or just maternal genes and the cerebral cortex had no paternal genetic material whatsoever. This is the area of the brain responsible for logical reasoning, language, advanced thinking and planning.
This idea that mothers have a much greater influence on their children’s cognitive thinking is nothing new, it was first researched back in 1984 by Cambridge University, which also concluded that the maternal genes have a greater contribution on our brain development.
The latest study we analyzed in this article only further demonstrated these former findings. Although more research is needed on the topic, the results from both studies offer an extensive insight into how our intelligence in forged and how our genes are formed. It looks like we’ll have to thank mom for making us so smart and intelligent.
