What determines the baby's appearance? Who does he inherit?

For parents, the baby's appearance is something they have already imagined when the baby is still a fetus. In fact, the baby's appearance follows the laws of genetics. Parents can read the following to speculate what their baby will look like~

When it comes to appearance, parents each have their own advantages

Sons are more like their mothers, and daughters are more like their fathers. Is this really true?

From a genetic point of view, when the sperm and egg meet, the final pairing of chromosomes often results in the son's half of the mother's genes being more likely to be present. This is the genetic and physiological basis for boys to resemble their mothers. Since the X chromosome has two long and obvious arms, while the Y chromosome has one very short and inconspicuous arm, the mother's genes inherited by boys are more likely to be expressed dominantly. It is reasonable that the son inherits more genetic information from his mother and is more like his mother.

As for the fact that daughters are more like their fathers, one explanation is that this is because the X chromosomes from the mother are often "masked" by the X chromosomes from the father.

American psychologist Christian Fide believes that appearance is more inherited from the father. He explained that it may be because the father gives his children genetic characteristics, so the baby's face looks more like the father no matter how you look at it. The scientist further explained that this is also a manifestation of the human instinct of "self-preservation", because there is no doubt who the mother is, but who the father is not so sure, so the baby must look like the father, which is good for the baby and can also encourage the father to invest more love.

As for skin color, eye shape, nose, ears, etc., specifically, it is like this:

Skin color: It follows the natural law of "multiplying and then averaging". If the parents have dark skin, then their children's skin will definitely not be fair and tender. If one parent is fair and the other is dark, most of the time the children will have a "neutral" skin color, but there are also cases where they are more biased towards one side.

Double eyelids, eye shape, eyelashes, nose, ears, jaw: these are dominant traits. In other words, if one of the parents has big eyes, double eyelids, long eyelashes, a high nose bridge, big ears, and a protruding chin, the child is likely to have these traits as well.

Eye color: Dark colors such as black are dominant over light colors. In other words, people with black and blue eyes are more likely to have children with black eyes.

Baldness: God seems to favor women, allowing baldness to be passed on only to men. For example, if the father is bald, there is a 50% chance that the baldness will be passed on to the son. Even the mother's father will have a 25% chance of passing on his baldness to his grandson.

However, parents should not take the above statements too seriously, just understand them with an entertaining attitude.

How to optimize your genes before your baby is born

——My husband and I are both dark-skinned, but I don’t want the baby we give birth to to be a dark angel.

——If black couples want to have white babies, pregnant women can eat more foods rich in vitamin C. Vitamin C interferes with the production of melanin in the skin, reduces melanin deposition, and the baby's skin will be white, tender and delicate.

Recommended foods: tomatoes, grapes, citrus fruits, cauliflower, winter melon, onions, garlic, apples, sea buckthorn, fresh dates and other vegetables and fruits, among which apples are the best.

——My husband and I both have dry skin, which is prone to chapped skin in winter. How can we prevent our baby from suffering from this?

——The couple has rough skin, and pregnant women should eat foods rich in vitamin A regularly, which can protect skin epithelial cells and make the child'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.

——My family has a gene for yellow hair. My sister's child is now one year old and still has yellow hair. Will my baby also inherit this gene?

——If a couple has bad hair, the pregnant woman can eat more foods containing B vitamins, which can improve the child's hair quality, making it thick, black, and shiny.

Recommended foods: lean meat, fish, animal liver, milk, bread, beans, eggs, seaweed, walnuts, sesame, corn and green vegetables.

Music can make your baby's appearance more beautiful

A person's joy, anger, sorrow, and happiness are all generated by receiving information from the outside world. That is, the information is transmitted to the brain through organs such as ears and eyes, and the brain then processes and assigns changes to the nerves in a certain part of the face.

Compared with children who often receive sad, fearful, frightened and unpleasant information, certain facial muscles of children are fundamentally different from those who often receive happy, joyful and joyful information. Because the brain nerves keep certain facial muscles in a state of tension for a long time, happy or sad facial expressions are difficult to fade away and become fixed over time.

Letting children listen to cheerful music frequently, using music to stimulate nerves and regulate spirits, will help children grow up healthily physically and mentally. The Japan Early Childhood Development Association has conducted experiments on this point and achieved very good results. They gathered dozens of newborn children, took photos and videos one by one, and used them as raw materials. Then they played Mozart's serenade three times a day in the morning, afternoon and evening. There was no change at the beginning, but after four months, the faces of these children changed a lot, their expressions were more lively than those of ordinary children, their movements were coordinated, and even their eyes were fundamentally different from those of ordinary children.

It can be seen from this that letting children listen to more beautiful music in their early childhood is not only beneficial to their intelligence, but also can make them more beautiful.
