Who is the child's height and thinness? Guide: Who is the height and thinness of a child? Father or mother? In order to find out this problem, British scientists have done a lot of fact checking and found that the height of the father usually affects the child, while the mother determines the degree of obesity of the child to a greater extent. Compare yourself with your parents if you don't believe me! Why is this truth? Let's explain it from a genetic point of view. First, absolute genetic skin color: people have no choice. It always follows the natural law of parents' "neutral" color. For example, parents with dark skin will never have children with * * * skin; If one side is white and the other side is black, most children will be given a "neutral" skin color that is neither white nor black after being "averaged" in the embryo, but there are also cases that are more biased to one side. Jaw: it's a dominant inheritance, so you can't "discuss". "Image" makes you helpless. For example, even if either parent has a prominent chin, children often have similar chins without exception, which is somewhat bizarre. Double eyelids: it is also an "absolute" inheritance. Interestingly, most of the father's double eyelids will be left to the children. Some children are born with a single eyelid, and when they grow up, they will "fill" the double eyelids like his father. In addition, big eyes, big earlobes, high nose and long eyelashes are the most characteristic inheritance that can be obtained from parents when the five senses are inherited. Second, hereditary obesity has a probability of more than half: it will make children have a 53% chance of getting fat. If one parent is obese, the probability of children being obese will drop to 40%. This shows that about half of being fat can be determined by human factors. Therefore, parents can make their posture symmetrical through reasonable diet and adequate exercise.
Does a person's height and appearance depend on nature? Height is determined by nature by 70% (fetal period-1.5 years old, 70% of the height of a given life).
Appearance is 70% determined by the day after tomorrow (the modification, modification and cultivation temperament of the day after tomorrow determine 70% of a person's appearance)
The sex of the child depends on who is pregnant, if it contains X chromosome (girl) and Y chromosome (boy).
Every cell in human body (including germ cells) has 23 pairs of chromosomes carrying genetic material, of which 22 pairs are autosomes, all the genes contained in the 23 pairs are genetic information, and 1 pair is a sex chromosome, which determines the sex of the fetus. The types of trait genes contained in autosomes are the same for men and women, and there is no gender difference. Sex chromosomes are different. The male 1 sex chromosome consists of X chromosome and Y chromosome (the male genome becomes 22+XY), while the female 1 sex chromosome is X chromosome (the female genome becomes 22+XX). Half of the 23 pairs of chromosomes come from the father and the other half from the mother.
The sex of a child is determined at the moment of fertilization, and the decisive factors are equally divided.
Whose genes determine whether a child is beautiful or not? No, external conditions are also important.
For example, how beautiful the child is, don't dress him or her.
Dress neatly. In the eyes of others, your child is just not beautiful.
In principle, children under two years old belong to the woman, and the man pays maintenance.
Children over two years old mainly look at which side is beneficial to their growth.
Does the child's cleverness depend on the mother? Is mother the key to children's intelligence? The answer is yes.
First of all, from a genetic point of view, whether a child is smart or not depends on the mother. Recently, British scientists believe that the genes that determine a child's intellectual development are located on the X chromosome, and the genes on the mother's X chromosome determine the development degree of the child's cerebral cortex, while the father's genes may have an important influence on shaping the emotions and personality types of future generations. According to this theory, it can be explained that boys are prone to "polarization", either extremely intelligent or mentally retarded, while girls are mostly average in intelligence. Therefore, if a woman wants her children to be smart, she doesn't have to find a husband with high IQ, while if a man wants his offspring to have high IQ, he has to marry a smart wife.
Secondly, the mother's cultural quality is closely related to prenatal and postnatal care. The research and analysis of eight maternity hospitals shows that the risk factors of fetal birth defects are closely related to the mother's cultural quality. The higher the mother's educational level, the lower the possibility of fetal defects. The reason is that women with low education will have the following effects on fertility:
① The rate of early marriage and childbearing is high, especially for illiterate or semi-illiterate women. Considering the obstetric physiology and eugenics, the best childbearing age is 25 ~ 29 years old. If a woman is born prematurely, because her advanced nervous system and skeletal system are not yet mature, she needs to undertake the task of nourishing the fetus during pregnancy, which may lead to nutritional deficiency such as anemia, edema and rickets of her mother. Fetal development is also affected. Most babies lack resistance to various diseases due to congenital deficiency and weakness, especially the birth rate of children with congenital stupidity has more than doubled.
There are many close relatives getting married. According to the survey, in 102, there are 5 couples with junior high school education or above, 32 couples with high school education, and 65 couples who are illiterate or semi-illiterate. Among them, four half-brothers or half-brothers are married, and they are completely illiterate. Genetic research has long confirmed that kinship will increase the occurrence of genetic diseases, cause deformities and harm future generations. The offspring of consanguineous marriage have high mortality and poor physical strength and intelligence.
③ The awareness of protection during pregnancy is indifferent. According to the investigation, among pregnant women with higher education, 7 1.3% have the consciousness of actively protecting the fetus; While illiterate and semi-illiterate pregnant women only accounted for 45.7%.
4 affect children's intellectual development. For several years, children's health care experts in China have been exploring the influence of family environment on children's intellectual development. The results show that in terms of language, the total scores of environment and IQ are higher, and most mothers have higher cultural literacy. They not only demand their own study, but also attach importance to their children's education. They are willing to spend time telling stories to children and answer their questions patiently.
Third, the mother's concept of nutrition, family economic status and scientific knowledge of nutrition are very important for the baby's intellectual development. They know how to make children have a smart head, grasp the golden period from pregnancy to the age of 6 after birth, and have a reasonable and balanced diet, especially continuous and sufficient supplementation of DHA and lutein. We should also know that DHA and lutein can complement each other better. Retina is rich in DHA unsaturated fatty acids, and DHA is easily oxidized. If lutein is lacking, DHA supplementation will greatly reduce the development and health care of retina, and the antioxidant protection of lutein in macular area can protect retina from fat oxidation. For example, the compound soft capsule extracted from seaweed by Newlitz not only has scientific DHA content and good quality, but also specially adds lutein, which can ensure the baby's needs, better protect DHA from oxidation and have better absorption and utilization effect. Lutein is the only carotenoid that can exist in the lens, which can improve the antioxidant capacity of the lens, resist the damage of ultraviolet rays and free radicals, protect the microvasculature of the eye, maintain good blood circulation, effectively prevent and relieve amblyopia, improve vision and make the brain more developed.
Is it really up to parents to make their children shorter? 70% or even 80% of short stature depends on parents, and children inherit their parents' dominant genes, so your own children are basically no taller than the tallest one, especially girls inherit their father's height and boys inherit their mother's height.
