Does a child inherit his IQ from his father or mother?

IQ is a relatively important ability for an individual. If a person has a high IQ, he or she can solve various problems well whether in work or in the learning process. Generally speaking, IQ is hereditary to a certain extent. So, is a child's IQ determined more by the father or the mother? Let me answer your questions below.

1. How is height inherited?

Under the premise of nutritional conditions, 70% of the initiative of a child's height is in the hands of his parents. The parents' genetics are the main factor determining the child's height, because 35% of the factors that determine height come from the father and 35% from the mother. If both parents are not tall, then it depends on the baby's 30% effort.

2. How is intelligence inherited?

Intelligence is somewhat hereditary, but is also influenced by acquired factors such as environment, nutrition, and education. According to scientists, genetics accounts for about 50%-60% of the influence on intelligence. In terms of genetics, if the mother is smart, the child she gives birth to will mostly be smart. If it is a boy, he will be even smarter. The reason for this is that the genes related to human intelligence are mainly concentrated on the X chromosome. Women have two X chromosomes and men only have one, so the mother's intelligence plays a more important role in heredity.

3. How is personality inherited?

Personality is largely inherited from the father. The formation of personality certainly has innate components, but it is mainly influenced by later factors. Comparatively speaking, father's influence is greater than mother's. Among them, the role of fatherly love has a greater impact on daughters. A psychologist believes: "Fathers play an important role in the formation of their daughters' self-esteem, sense of identity and gentle personality." Another expert suggested that fathers can teach their daughters many important lessons and experiences in life, making their daughters' personalities more colorful.

4. How to optimize genes before the baby is born?

Studies have shown that air pollution can affect embryo quality and even cause embryo arrest. Experts suggest that during foggy weather, women of childbearing age should postpone pregnancy and pregnant women should reduce outdoor activities. Consider getting pregnant one month after the haze has cleared.

PM2.5 contains a variety of heavy metals and polycyclic aromatic hydrocarbons (a carcinogen), which can cause fetal blood poisoning, leading to delayed intrauterine development and reduced birth weight. Toxic substances can skip the placenta and directly affect the fetus, especially in early pregnancy. In severe cases, it can even cause stillbirth.
