Researchers found out that children inherit the mental abilities or intelligence of their parents for about 40-60%, while the intelligence genes were found only on the X chromosome. So mothers are the real heroes.
In other words, smart people owe their abilities especially from mothers, because basically they are responsible for the transfer of genes that affect intelligence.
It was found that the kids who got most of the maternal genes have a larger brain volume, but smaller body size. And those who got more genes from Dad, everything is exactly the opposite. During the growth of the embryo cells containing paternal genes ensure its survival. They are concentrated in the limbic system of the brain, which is responsible for aggression, hunger and sex.
However, the researchers argue that the father’s cells were not found in the cerebral cortex – the same area where development of the most important human cognitive functions: intelligence, thinking, planning and language skills happen.
Whatever it was, we should not forget that the mental abilities are not 100% due to genetics. Other studies show that mothers play an important role in the intellectual development of children through the physical and emotional contact. That is, the relationship between the mother and the child is largely influenced by her intellect.
The study’s authors argue that children who have developed a strong relationship of trust with their mothers exhibit more persistence in achieving goals, and are less likely to show disappointment at the decision of complex problems. Researchers from the University of Washington (USA)found that a strong emotional bond between mother and child is crucial for the normal development of certain areas of the brain. Scientists also believe, a strong relationship with the mother provides the child a sense of security, and gives an opportunity to explore the world.
Regardless of what they say about genetics, dads should not feel disadvantaged. Being emotionally available for a baby and becoming a role model, a father contributes to a child’s development as well as the mother.
Intelligence quotient (IQ), which we are born, can play an important role, but ultimately it is not the decisive factor. But it is time to pay more attention to intellectual mothers.
