Sudy: IQ from Mother and Father Genes Affect 3 Aspects
Everyone wants their children to be smart and smart, but in fact, IQ is also affected by genes, and it depends on the mother ’s genes, but the mother does not have to be too stressed. Researchers emphasize that genetics is not the only determinant of IQ. Only 40-60% are related to heredity, the others come from environmental factors.
The researchers found that the X chromosome has an IQ gene. Since women have two X chromosomes and men have only one, the child’s IQ gene is more likely to come from the mother, and genes inherited from the father’s higher cognitive functions may be automatically disabled .
Some of the genes classified as “conditioned genes” must be inherited from the mother to function. If the same gene is inherited from the father, it cannot function. IQ is one of the genes that must be derived from the mother.
Scientists have also found through mouse experiments that in the cerebral cortex, which mainly controls important cognitive functions such as reasoning, thinking, and language, cells of the mother’s genes have also been found, but cells of the father’s genes have not been found. Cells of the paternal gene mostly appear in the limbic system involving sex, food, and aggression.
Researchers have also demonstrated the inferences from mouse experiments on humans and used a more human approach to explore IQ. Since 1994, they have interviewed 12,686 young people aged 14 to 22 and found that IQ is indeed affected by the mother’s genes. Of course, acquired education and nutrition can also affect intellectual development. In the IQ test, children who live in safe, loving, and well-nourished families tend to get higher than those who live in conflicting and malnourished environments. fraction.

Close relationship with mother helps children develop
In addition to genetic effects, mothers still play an important role for children. The University of Washington study found that the emotional connection between mother and child is an important factor in brain development. The researchers took 7 years to observe and found that children with mother’s emotional support and intellectual needs are hippocampus at 13 years old. 10% older than a child without a mother.
The hippocampus is an area that controls associated memory, learning, and stress response. People receive a lot of information every day and generate many new experiences. They will enter all areas of the cerebral cortex and organize them in the hippocampus. They form short-term memories and then organize , Choose, send back to the cerebral cortex, and become long-term memory. A research report from the University of California, San Francisco, United States also shows that when people are about 13 years old, the hippocampal area seems to stop producing nerve cells, which shows how much mothers have influence on children.
A close relationship with the mother can make the child feel more secure, make them courageous to explore the world, and have the confidence to solve the problem, especially the responsible and attentive mother tends to help the child solve the problem, and also helps the child to realize his potential.
