It is often believed that intelligence, meaning sharpness and wisdom, is passed down from parents to children. However, genetic research shows that the intelligence of sons is primarily inherited from their mothers. This is because the mother's genes, along with her chromosomes, play a significant role in the development of the child's mental abilities.
Some studies also suggest that the father's genetics play a role in passing on intelligence, but mainly it is reflected in daughters. If the father is a genius, his daughters may inherit about half of his abilities. However, daughters pass on these abilities to their sons at a rate of 100%, highlighting the importance of intelligence inheritance through the maternal line.
Therefore, genetic inheritance within the family plays a crucial role in the intellectual abilities of children. These studies confirm that not only the traits of the parents but also their ancestors play a key role in the transmission of intellectual capabilities.
