1. Mothers have a greater influence on boys' IQ.
According to scientists' assessment, the influence of heredity on intelligence accounts for about 50%-60%. A large part of children's IQ is influenced by their parents' inheritance.
However, the genetic genes of human intelligence are mainly concentrated on the X chromosome, and the two X chromosomes of women have more genetic advantages than the male 1 chromosome.
If a girl's IQ is influenced by her parents, then a boy's intelligence is completely influenced by her mother's genes. So if you give birth to a very clever boy, you should praise your mother's excellent genes.
2. Height has the same influence on parents.
There are many factors that affect children's height, 70% of which are genetic factors of parents, and a large part of children's height depends on parents' heredity.
Some people are struggling. If one parent is short, will it also affect the height of the child?
Actually, don't worry too much. The height of a child is influenced by both husband and wife, and it is also accompanied by acquired factors: diet, sleep and transportation. 3. The supplement of exercise, emotion and nutrients can help children grasp the "golden growth period" of height.
3. The dominant side of the eye
Many people have the impression that "the daughter's eyes follow the father and the son's eyes follow the mother", but this is not the case. In the inheritance of eyes, whoever has the advantage will have the genetic advantage. If one of the husband and wife has double eyelids, big eyes, long eyelashes and dark pupils, there is a great chance that the child's eyes will look like him.
Some parents will wonder: If we both have double eyelids and big eyes, is it possible to give birth to a child with small eyes and single eyelids? It is still possible. But if you are a parent with two small eyes and one single eyelid, it is impossible to give birth to a child with big eyes and double eyelids.
4. The child's skin color is neutralized by parents.
Children's skin color generally follows the natural law of parents' "neutral skin color". If the parents' skin color is black and white, then the child is likely to have a neutral skin color of black and white, and a small probability will favor one side's skin color.
If both husband and wife have dark/white skin color, then the child will probably inherit the skin color of his parents. As the saying goes, "One white covers a hundred ugliness". If you want your child to have fair skin, it is also important to get sunscreen the day after tomorrow. Pay attention to diet during pregnancy.
The girl's character is more influenced by her father.
Although the formation of personality has innate factors, it is more important to be influenced by the acquired environment. Comparatively speaking, the father has a greater influence on the formation of his daughter's character.
A survey by the University of Michigan in the United States found that 69% of girls think that their self-confidence comes more from their fathers' praise and encouragement, and 40% of girls show that their ability to communicate with men is related to their fathers.
Fathers play a very important role in the formation of their daughters' sense of self-esteem, identity and personality. If the father often ignores, scolds and criticizes his daughter, it will greatly weaken her self-esteem and lead to the child's lack of self-confidence. In order to cultivate children with good personality, parents must set an example and make their words and deeds the best teachers for their children.
6. The child's fatness is determined by heredity and acquired.
A child's body shape will be influenced by his parents' inheritance.
If only one parent is obese, then the probability of children being obese is about 30%; If both parents are obese, then the probability of children getting fat is about 50%-60%. Although parents have a genetic influence on children's obesity, the acquired diet, exercise and lifestyle are the key to determining children's figure. Although genetic inheritance is important, it is not the only factor that determines a child. A child's growth is inseparable from the influence of the environment in the next seven days.
Myopia is related to heredity and eye habits.
According to a study, the incidence of myopia among school-age children aged 0/0 in China and Shanghai is 52.2%, and the average incidence of myopia among adolescents aged 6- 18 in Beijing is 70.9%. This study holds that high myopia is a multifactorial and/or monogenic genetic disease, and its genetic modes include autosomal dominant inheritance, autosomal recessive inheritance and sex-linked recessive inheritance.
In addition to genetic reasons, excessive use of eyes, reading too close to the book, lying down and other wrong reading postures will lead to decreased vision. There are many hazards of myopia, such as vision loss, strabismus, glaucoma, lens opacity and so on. Therefore, parents must pay attention to their children's eye habits and use their eyes scientifically to reduce the occurrence of myopia.
8. Depression
A number of patients with affective disorder, including depression, mania and bipolar disorder, were investigated, and a consistent conclusion was reached: the comorbidity rate of patients with affective disorder and their first-degree relatives was higher than that of their second-degree relatives, and the prevalence rate of relatives was higher than that of ordinary people, that is to say, the closer the blood relationship, the higher the prevalence rate of depression.
With regard to depression, full understanding and care from the outside world will reduce the incidence rate to a certain extent, and we should also pay more attention to our inner health, don't give up on ourselves, and try our best to discover the beauty in life.
