Mother’s genes go directly to the cerebral cortex, those of the father to the limbic system
In practice, during the first days of the embryo development, any cell can appear anywhere in the brain, but to the extent that the embryos mature and grow, cells that had the paternal genes accumulate in some areas of the emotional brain: hypothalamus, amygdala, the preoptic area and the septum. These areas are part of the limbic system, which is responsible for ensuring our survival and is involved in functions such as sex, food and aggression. However, researchers have not found any paternal cells in the cerebral cortex, which is where they develop the most advanced cognitive functions, such as intelligence, thought, language and planning.
New studies, new lights
Genetics is not the only responsible
Can we really talk about hereditary intelligence?
Beyond what was stated by genetics, fathers should not be discouraged, because they also have much to contribute to the development of their children, especially being emotionally present. The IQ with which we are born is important, but not decisive.
