Which of the couple\’s genes determines the child\’s IQ and appearance? So accurate

Even before the baby is born, mothers will argue with the father about whether the child in the belly is a boy or a girl and who it looks like? What do you want the baby to look like? Eyes like yours and nose like his? His body is like yours and his IQ is like him? But whose genes determine everything about the child? Below, let us find out together! Height inheritance: half from each parent. In addition to nutritional status, 70% of the initiative in a child\’s height is in the hands of parents. Parents\’ genetics is the main factor that determines a 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. Intellectual inheritance: mother. Intelligence is hereditary to a certain extent and is also affected by acquired factors such as environment, nutrition, and education. According to scientists\’ assessment, genetics accounts for about 50% to 60% of the impact on intelligence. In terms of genetics, if the mother is smart, most of her children will be smart, and if they are boys, they will be smarter. The reason is that 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 occupies a more important position in heredity. To prove this point, let’s first review high school biology knowledge: how baby boys and girls come about. Boys are XY, X (egg) comes from the mother, and Y (sperm) comes from the father. Girls are XX, X (egg) comes from the mother, and X (sperm) comes from the father. Therefore, it is the husband\’s fault to have a boy or a girl. Don\’t blame the mother for her belly failure. Please note that boys are XY, so a boy’s IQ is all inherited from his mother, and girls are XX, so a girl’s IQ is half influenced by her father and half her mother. Because girls’ IQ is influenced by both their father and mother, there will be a neutralizing effect, so the distribution of girls’ IQ will show a natural distribution (normal distribution), which is an inverted bell shape, with most in the middle and less on both sides. And because boys are completely affected by only one side, the IQ distribution of boys will be biased towards two extremes. In other words, there are more geniuses among boys, but at the same time, there are also a lot of idiots among boys. These tell us: 01. To judge whether a boy is smart or not, just look at his mother. 02. Then we use probability to calculate: the probability of giving birth to a boy = 1/2; the probability of giving birth to a girl = 1/2. When a boy is born, the mother’s influence on the boy’s IQ = 1. When giving birth to a girl, the mother’s influence on the girl’s IQ = 1/2. So, if you: 01. Are a boy and feel stupid, you must marry a smart girl. In this way, your child has a 75% chance of making a comeback, and life is still full of hope. 02. If you are a girl, you feel stupid because there is a 75% chance of you overturning someone else\’s game, so try your best to have a girl. 03. When you see a boy who is very smart, the probability that his father is very smart is 0% (it should be said that even if his father is very smart, it has no impact on him), but the probability that his mother is very smart is 100%. So, if you are thinking about marryingWhen you have a very smart boy, you have to be careful about his mother, who may be a very calculating mother-in-law. Personality inheritance: Dad. Personality is inherited from the father. Although there are innate components to the formation of personality, it is mainly due to acquired influences. Comparatively speaking, the influence of father will be greater than that of mother. Among them, the role of father\’s love has a greater impact on daughters. A psychologist believes: \”Fathers play an important role in the formation of a daughter\’s sense of self-esteem, identity and gentle personality.\” Some experts have suggested that fathers can teach their daughters many important lessons and experiences in life. Make your daughter\’s character more colorful. Physiological inheritance: specific analysis of specific issues. Skin color: always follows the natural law of \”multiply and then average\”, leaving people with no choice. If the parents have dark skin, they will never have fair-skinned children; if one parent is white and the other is dark, most children will have a \”neutral\” skin color, and there are cases where one parent is more likely to have fair skin than the other. Eye shape: The child\’s eye shape and size are inherited from the parents. Large eyes are dominantly inherited compared to small eyes. If one parent has big eyes, the child with big eyes may be older. Double eyelids: Double eyelids are a dominant inheritance. Children with single eyelids and double eyelids are very likely to have double eyelids. But both parents have single eyelids, and most children also have single eyelids. Eye color: Dark colors such as black are dominantly inherited compared to light colors. In other words, children with black eyes and blue eyes will not have blue eyes. Eyelashes: Long eyelashes are also dominantly inherited. As long as one parent has long eyelashes, the child is more likely to inherit long eyelashes. Nose: Generally speaking, a large, tall nose and wide nostrils are dominantly inherited. If one of the parents has a straight nose, there is a high possibility that this will be passed on to the child. The genetic inheritance of the nose will continue into adulthood. A short nose in childhood may become a tall nose in adulthood. Ears: The shape of ears is hereditary. Large ears are dominantly inherited compared to small ears. As long as one of the parents has big ears, the child will most likely also have big ears. Jaw: It is a dominant inheritance that is not “negotiable”. If either parent has a protruding chin, their children will always have a very similar chin, which is a bit bizarre. Obesity: Children have a 53% chance of becoming obese. If one parent is obese, the probability of the child being obese drops to 40%. This shows that about half of whether one is fat or not can be determined by human factors. Therefore, parents can completely maintain a well-proportioned body shape through a reasonable diet and adequate exercise. Baldness: The Creator seems to have favored women and allowed baldness to be passed on only to men. For example, if a father is bald, there is a 50% chance of passing it on to his son. Even the mother\’s father will pass on a 25% chance of being bald to his grandchildren. Acne: This facial disease that bothers boys and girls is actually related to heredity. Because if both parents have suffered from acne, the children\’s incidence will be 20 times higher than those without a family history. Leg shape: Legs that resemble the fat accumulation of your parents can be shaped into slender and strong legs through adequate exercise. On the other hand, if the legs are too long or too short due to genetics, they cannot be reshaped and can only be left to nature. How to be there before your baby is bornBefore, optimizing your genes? 01. My husband and I both look quite dark, but I don’t want the baby I give birth to to be a dark angel. If a black couple wants to have a white baby, pregnant women can eat more foods rich in vitamin C. Vitamin C interferes with the production of melanin in the skin and reduces melanin deposition, making the baby\’s skin white, tender and delicate. Recommended foods: tomatoes, grapes, citrus, cauliflower, winter melon, onions, garlic, apples, prickly pears, fresh dates and other vegetables and fruits, among which apples are the best. 02. My husband and I both have dry skin, which easily gets chapped in winter. How can we protect our baby from this problem? If couples have rough skin, pregnant women should often eat foods rich in vitamin A, which can protect skin epithelial cells and make their children\’s skin delicate and shiny in the future. Recommended foods: animal liver, egg yolk milk, carrots, tomatoes, green vegetables, fruits, dried fruits and vegetable oils, etc. 03. My family has a gene for inheriting yellow hair. My sister’s child’s hair is still yellow when he is one year old. Will my baby also inherit this gene? If a couple\’s hair is not good, pregnant women can eat more foods containing vitamin B, which can improve the quality of their children\’s hair, making it not only thick and black, but also shiny.
