You must be arguing with the father about whether the baby is a boy or a girl? Who will it look like? What do you want the baby to look like? Eyes like you, nose like him? Body like you, IQ like him? Then you have to find out what genes determine this? Whose genes are responsible for height? –Parents’ genetic inheritance is the main factor in determining a child’s height, because 35% of the factors determining height come from the father and 35% from the mother. If both parents are not tall, it is up to the baby to make that 30% effort later in life. Whose genetic predisposition to intelligence is greater? –Mother Intelligence has a certain hereditary nature and is also influenced by environmental, nutritional, educational and other acquired factors. Scientists have assessed that heredity has about 50-60% influence on intelligence. As far as heredity is concerned, a smart mother gives birth to a mostly smart child, and if it is a boy it will be even smarter. The reason for this is that the human genes related to intelligence are mainly concentrated on the X chromosome. Women have two X chromosomes, while men have only one, so the mother’s intelligence takes a more important place in the genetic heritage. To prove this point, let’s first review our high school biology knowledge: How do male and female babies come about? Boys are XY, X (egg) is from the mother and Y (sperm) is from the father. A girl is XX, X (egg) is from the mother and X (sperm) is from the father. So it’s the fault of the gentleman, don’t blame the mother’s belly for not fighting. Please note: The boy is XY, so the boy’s IQ is all from the mother’s genes, the girl is XX, so the girl’s IQ is the father and mother each half influence. Because the IQ of girls is the influence of both mother and father, so there will be a neutralizing effect. So the distribution of girls’ IQ will show a natural distribution (normal distribution), that is, inverted clock shape, the middle is the most, the two sides less. Then boys are completely influenced by only one side, so the distribution of male IQ will be biased in the two extremes. In other words, there are more male geniuses, but at the same time, there are also more male idiots. What does this story tell us? 1, you want to judge whether a boy is smart, look at his mother will know. 2, then we use the odds to calculate: the odds of having a boy = 1/2; the odds of having a girl = 1/2. When you have a boy, the mother’s influence on the boy’s IQ = 1 When you have a girl, the mother’s influence on the girl’s IQ = 1/2 So, if you: 1, are a boy, if you think you’re stupid. You must marry a smart girl to. So that the chances of your child turning over there are still seventy-five percent, life is still full of hope. 2, is a girl, if you think you are very stupid, because, the chances of you turning over people’s plates have seventy-five percent …. Try to have a female child. 3, when you see a boy is very smart, then, his father is very smart chance is 0% (should say, even if his father is very smart, but also to him is no effect), but his mother is very smart chance is 100%. So, if you are considering marrying a very smart guy, you should be careful of his mother, who may be a very calculating mother-in-law. Conversely, when you see a guy is very stupid, yes, he will usually be very rich, this is God’s arrangement, God in order to keep mankind from extinction, so he will make very stupid people very rich, so that he can marry smart girls. Whose genetic heritage is big in personality? –Dad Personality is inherited from the father. The formation of personality certainly has an innate component, but mainly after the influence. Comparatively speaking, the father’s influence will be greater than the mother’s. Among them, the role of the father’s love has a greater impact on the daughter. According to one psychologist, “Fathers play an important role in their daughters’ sense of self-esteem, identity, and the formation of a gentle personality.” Another expert suggested that fathers can impart many important life lessons and experiences to their daughters, resulting in a more colorful personality. Whose genetic heritage is greater for looks? –Skin color: always follows the natural law of “multiply and average,” leaving no choice. If the parents have dark skin, they will never have children with white skin; if one side is white and one side is black, most of them will give their children a “neutral” skin tone, but there are also cases where one side is more inclined. Eye shape: The child’s eye shape and size is inherited from the parents, and large eyes are dominant over small eyes. If one parent has large eyes, the likelihood of having a child with large eyes will be greater. Double eyelids: Double eyelids are dominantly inherited, and a baby born with single eyelids and double eyelids is very likely to have double eyelids. However, if both parents are single-eyed, usually the child is also single-eyed. Eye color: Dark colors such as black are dominant relative to light colors. In other words, people with black and blue eyes will not have children with blue eyes. Eyelashes: Long eyelashes are also dominantly inherited. As long as one parent has long eyelashes, the child is very likely to inherit long eyelashes. Nose: Generally speaking, a large, high nose with wide nostrils is dominantly inherited. If one parent has a straight nose, the likelihood of passing it on to the child is high. The genetic inheritance of the nose will continue into adulthood, and a short nose as a child may become a tall nose as an adult. Ears: The shape of the ears is inherited, and large ears are dominant relative to small ears. As long as one parent has large ears, the child will most likely have a pair of large ears. Jaw: This is a non-negotiable dominant trait. If either parent has a large, prominent jaw, the child will often have a similar jaw without exception, making the “resemblance” somewhat bizarre. Obesity: children have a 53% chance of becoming fat, if one parent is obese, the probability of the child being obese drops to 40%. This shows that fat or not fat, about half can be determined by human factors, so parents can make their own body shape through reasonable diet, adequate exercise. Baldness: The Creator seems to favor women by allowing baldness to be passed on only to men. For example, if a father is bald, the probability of passing it on to his son is 50%, and even the mother’s father will leave 25% of the probability of his baldness to his grandchildren. This tendency to pass on the sexes to men and not women makes men helpless. Acne: This is a nagging face disorder for young boys and girls, but it is also related to genetics. If both parents have suffered from acne, the children will be 20 times more likely than those with no family history. Legs: The fatty legs of the parents can be shaped into long and strong legs with adequate exercise. However, if the legs are too long or too short due to genetics, they cannot be reshaped and are left to nature. How to optimize your genes before your baby is born? 1, my husband and I both look quite dark, but I do not want to give birth to a baby who is also a black angel. –The black couple wants to have a white baby, pregnant women can eat more vitamin C rich foods. Vitamin C has an interfering effect on skin melanin production, reducing melanin deposits, the baby’s skin will be white and delicate. Recommended foods: tomatoes, grapes, citrus, cauliflower, winter melon, onions, garlic, apples, prickly pears, fresh dates and other vegetables and fruits, of which apples are the best. 2, my husband and I are dry skin, once the winter is very easy to crack, how can I make the baby does not suffer this crime? –Couple rough skin, pregnant women should always eat foods rich in vitamin A, can protect the skin epithelial cells, so that later the child’s skin delicate and shiny. Recommended foods: animal liver, egg yolk milk, carrots, tomatoes, as well as green vegetables, fruits, dried fruits and vegetable oils. 3, my family has inherited the gene of yellow hair, my sister’s child is now one year old hair is still yellow, my baby will also be inherited ah? — If the couple has bad hair, pregnant women can eat more food containing vitamin B, which can make the child’s hair quality improved, not only thick, black, and shiny and oily. Recommended foods: lean meat, fish, animal liver, milk, bread, beans, eggs, nori, walnuts, sesame, corn, and green vegetables.
