Until now, we supposed that intelligence is based on a father’s genes as much as the mother’s. But according to the new study, intelligence depends on a mother’s X chromosome. Intelligence genes are situated in mother’s X chromosome. Thus, intelligent mom has intelligent kids even if their fathers aren’t that much smart. This study was held by the scientists from the University of Cambridge.
The ‘conditioned genes’ behave differently depending on their origin. It has a kind of biochemical tag which allows tracing the origin. Thus, it unveils even if they are active or not within the progeny cells. If that same gene is hereditary from the father, it is deactivated. Obviously, other genes work the opposite. They activate only if they arriving from the father.”
According to this new study, woman’s genes go directly to the cerebral cortex, in an embryo. They play a vital role in attention, memory, awareness, perception, thought, language, and consciousness. Similarly, father’s genes go to limbic system. They are vital and responsible for growing tissue which will shape the placenta.
Scientists found that when the created embryos consisting only mother genes, are transferred into the uterus. They then die. Hence, it is proved that the conditioned genes are activated just when inherited from the mother. It was a big deal and has been a key to understanding the co-evolution of the brain and the conditioning of the genome.
Additionally, if these genes are important for the development of the embryo, it should also play the main role in the lives of animals and people. But the problem was how to prove why embryos which have only one parent’s genes died quickly.
It suggests that intelligence corresponds with the quality relationship between parents and children.
Surely intelligence is also related with the high-quality relation between parents and children. The kids who had a strong attention in first years are more able to solve problems. Additionally, they are passionate about it, but it is great to know that our mothers are really awesome!
