Who determines the IQ of the fetus? What does the IQ of the fetus relate to?

Who determines a child's IQ? Many people mistakenly believe that it is the father's genes that determine the child's IQ. In fact, the mother has a greater influence on the child's intelligence. If you don't believe it, follow the editor to see~

Who determines the IQ of the fetus?

★The mother's intelligence has a greater impact on the fetus' intelligence

According to the research results of Australian scientists, this is because the genes related to human intelligence are mainly concentrated on the X chromosome. Women have two X chromosomes, while men have one X chromosome and one Y chromosome; at the same time, the mother's X chromosome gene determines the degree of development of the child's cerebral cortex, while the father's gene has a greater influence on shaping the emotions and personality of the offspring. Therefore, the mother's intelligence occupies a more important position in genetic factors. According to relevant data, if the father has low intelligence and the mother has normal intelligence, the chance of the children having low intelligence is less than 10%; if the mother has low intelligence and the father has normal intelligence, the chance of the next generation having low intelligence is greater than 10%. It can be seen that the saying that smart mothers give birth to smart children is scientifically reasonable.

★Mothers have a greater influence on their children through their acquired environment and education.

Michel Duym, a famous French geneticist, believes that "although certain genes that play an important role in the development and operation of brain cell nerves are inherited, this does not mean that intelligence is completely related to genetics, because the development of intelligence is affected by the environment. For example, the environment during the mother's pregnancy and delivery, as well as the family environment, may also cause differences in children's intellectual development, resulting in different IQs. Moreover, even if a child inherits certain smart characteristics of his parents, these characteristics will be completely changed due to different acquired environments."

★Mothers with high cultural literacy have a higher awareness of protecting the fetus.

In this kind of postnatal influence, since the mother bears the heavy responsibility of nurturing, the mother's awareness of protecting the fetus also affects the child's future intelligence. Whether a woman has a sense of protection for the fetus is related to her cultural quality.

Generally, illiterate or semi-literate women have a high rate of early marriage and early childbearing. Due to early childbearing, their advanced nervous system and skeletal system have not yet matured, and they have to bear the task of nourishing the fetus during pregnancy, which can easily lead to nutritional deficiencies, anemia, edema, rickets and other diseases in pregnant women, which can also affect the development of the fetus, resulting in congenital deficiencies and weak constitutions in babies. The birth rate of children with congenital idiocy has also increased by more than 1 times. According to relevant data, 71.3% of pregnant women with a primary school education or above have a positive awareness of protecting the fetus, while only 45.7% of illiterate and semi-literate pregnant women do.

★The mother’s educational level affects the child’s intellectual development.

After a child is born, the mother often plays a more important role in family education than the father, so the mother's education level also affects the child's intellectual development. In recent years, my country's child care experts have conducted research on the impact of family environment on children's intellectual development. The results show that in terms of language, most mothers with high total scores and IQs have high cultural accomplishments. They not only require themselves to study, but also attach importance to children's education, are willing to spend time telling stories to children, and patiently answer questions raised by children.

Based on these points, the influence of mothers on children's intelligence is obviously greater than that of fathers. It seems that if a man wants to have a smart child, he must marry a smart wife, but a woman does not necessarily have to marry a smart husband.

Dr. Xu's warm reminder: Studies have shown that female longevity can be passed on to children, while male longevity is only passed on to males and not females. Scientists have pointed out that the length of human life depends largely on genetic factors, and children with a family history of longevity are more likely to inherit the longevity gene from their parents. However, the father's longevity gene is only passed on to his son, while the mother's longevity gene can be passed on to all children.

4 factors that determine whether a child is smart

No. 1: Genetics

Genetics is the primary factor that determines a child's IQ. The IQ of the parents directly determines the child's intelligence. In addition, the blood relationship of the parents will also affect the child's IQ. For example, in the past, families with close relatives marrying were prone to premature death, mental retardation, and physical disabilities, while those who were not related by blood would give birth to healthier children. In addition, if both parents are smart, the child will generally be smarter, because the baby will inherit the genes of the parents and will naturally be affected by the IQ of the parents.

No. 2: Diet

During pregnancy, if the expectant mother eats fish frequently, the child will be smarter, because the unsaturated fatty acids in fish will stimulate human nerves, promote brain development, and make the baby's brain develop better, which is beneficial to the child's IQ. In addition, after the child is born, in terms of acquired diet, the child can also eat more fish and seafood, which are beneficial to promote the child's brain development. When parents feed their children, they should also pay attention to supplementing their children with more vitamins, especially vitamin C, which is a good product for improving IQ. Therefore, it is recommended that pregnant mothers drink more fish soup during pregnancy to supplement calcium and vitamins. These nutrients will promote the brain development of the fetus. However, when eating fish, you should pay attention to avoid those marine fish with high mercury content, otherwise it will easily lead to threatened abortion and fetal malformation.

Impact Index: ★★★

No.3: Music

After 6 months of pregnancy, expectant mothers can listen to more music, because scientific research shows that music can promote fetal brain development and make children smarter. In addition, when the child is born, parents can also often play light music for the child to listen to, on the one hand, to prevent the child from crying too much, on the other hand, it can effectively stimulate the development of the child's brain cells.

Impact Index: ★★

No4: Age of marriage and childbearing

If a man gives birth to a child before the age of 30, the child's IQ will be higher. The same is true for women. If a woman is pregnant at an advanced age, it will not only affect the child's brain development, but also affect the child's physical health. For example, the child is more susceptible to congenital diseases. Therefore, the age of marriage and childbearing is very important. If you want to have a child, you should do it as early as possible, so that you can give birth to a smart and healthy child.

These ten foods reduce your baby's IQ

The IQ level of a child is also affected by many other factors, such as the weight of the pregnant woman, the educational level of the parents, etc. These factors will also affect the intelligence of the child. If your child is not doing well in school, don't just blame them, but also consider your own factors!

Stinky tofu smells stinky but tastes delicious. It is really satisfying to eat it with chili sauce. Preserved eggs mixed with tofu and sprinkled with some sugar and minced garlic for seasoning are really appetizing... Are pregnant mothers familiar with these delicious foods? The foods listed by the editor are believed to be the favorites of many pregnant mothers. However, these delicacies will unknowingly lower the IQ of the fetus.

Stinky Tofu

Stinky tofu is easily contaminated by microorganisms during the fermentation process. It also contains a large amount of volatile basic nitrogen and hydrogen sulfide. It is also a corrupt substance that decomposes protein, which is not good for the health of pregnant mothers.

Preserved Eggs

Preserved eggs contain a certain amount of lead, and regular consumption can cause lead poisoning in the human body. Symptoms of lead poisoning include insomnia, anemia, hyperactivity, intellectual impairment, etc., so pregnant mothers should eat less preserved eggs. Eating fresh eggs, duck eggs, etc. is the first choice for nutrition.

chewing gum

I believe pregnant mothers all have such a habit: chewing gum after meals to keep the mouth fresh, but chewing gum is not a good food.

Although the natural rubber in chewing gum is non-toxic, the first-grade white rubber used in making chewing gum is added with certain toxic additives such as vulcanization accelerators and antioxidants. Eating too much will be harmful to the body, so pregnant mothers should eat less. Brush your teeth if possible, otherwise rinse your mouth with boiled water, which will be more effective.

MSG

The daily intake of MSG per person should not exceed 6 grams. Excessive intake will increase the content of glutamate in the blood, limit the body's use of calcium and magnesium, and cause short-term headaches, palpitations, nausea and other symptoms, and also have adverse effects on the human reproductive system. Therefore, the editor recommends not adding MSG to the dishes for pregnant mothers.

coffee

Coffee contains a lot of caffeine. Once it is ingested and digested, it will quickly flow with the blood and reach various organs of the human body within 5 minutes, causing blood vessels to contract, metabolism to accelerate, and gastric acid and urine volume to increase.

Pickles

Pregnant mothers who eat pickled vegetables for a long time can cause sodium and water retention in the body, thereby increasing the chance of heart disease. In addition, pickled vegetables contain carcinogenic substances such as nitrosamines, which can easily induce cancer if eaten for a long time, so pregnant mothers should not touch pickled vegetables.

Dried fish slices

Some pregnant mothers like to chew dried fish fillets when they have nothing to do, but the pregnant mother's body does not like the delicious dried fish fillets. Chewing fish fillets for too long can waste saliva, and swallowing a large amount of saliva can dilute gastric juice and reduce digestion ability.

Popcorn

The lead content in popcorn is as high as 10 mg/500 g, which is harmful to the hematopoietic, nervous and digestive systems of pregnant mothers. So don’t think about sitting for two or three hours with a piece of popcorn in your hand when you go to the cinema.

Fried dough sticks

The alum in fried dough sticks is an inorganic substance containing aluminum. If you eat fried dough sticks every day, it will be difficult for aluminum to be excreted from the kidneys. Excessive aluminum in the body will be poisonous to the brain and nerve cells, which can have serious effects on the fetus.

Sweetened freshly squeezed orange juice

Some pregnant mothers like to drink orange juice with sugar added to neutralize the sour taste. However, orange juice with sugar added has higher calories and more sugar than soda. The editor still recommends that pregnant mothers eat oranges directly, which is healthier.
