The level of intelligence of the offspring is unrelated to the mother and father

The intelligence level of the offspring is inherited from the mother and father, the latest research shows that the child’s intelligence level is greatly affected by the mother. According to the British "independent" reported that the researchers found that the mother’s genetic genes determine the extent of her child’s intelligence, and his father did not affect. Women are more likely to pass on their genes to their children because they are carried on the X chromosome and women have two X chromosomes, while males have only one X chromosome. But in addition, scientists now believe that genes that are inherited from the father and are responsible for higher cognitive functions may automatically fail. A class of genes called "conditional genes" can work normally in some cases from a mother or father. The genes are thought to belong to this type of gene and are inherited from the mother. Researchers in the laboratory using transgenic mouse experiments, they found that those with more maternal mice developed larger head and brain, but smaller. But with more paternal gene of mice developed small head and big body. The researchers identified cells containing only maternal or paternal genes in six brain regions responsible for different cognitive functions. The cells that carry the gene of the father are clustered in the limbic system of the brain, involved in sex, food and aggression. But the researchers did not find any parent genes in the brain cortex, and the cortex involved in cognitive functions such as reasoning, thinking, language and planning. Researchers in Glasgow are worried that humans may not be the same as mice, and that they do more to explore human intelligence. They began to investigate 12686 young people between the ages of 14 and 1994, and the results of the study show that the results of the study of the mouse in the same way as the human race in. Although the survey also considered several factors, such as the level of education, race and socio-economic status of the test, but the researchers found that their intelligence is mainly dependent on the mother’s IQ. However, the study also found that genes are not the only determining conditions of intelligence, about 40%-60% of intelligence comes from genetics, the environment also has a similar effect. But the study found that the mother in the development of non genetic intelligence also plays a very important role, other studies have shown that emotional security between the mother and the child a combination is very important in some parts of the brain development of children. After 7 years of research, the researchers found that a close relationship with the mother of the children of the age of 13 than other children to develop a large body of the hippocampus of the body of 10%. The hippocampus is involved in memory, learning and stress response in the brain. (passenger compile)相关的主题文章:
