Who decides the child's appearance and height? You will know after reading this article.

"Is this child really nothing like you?"

My best friend said that she was most afraid to hear this sentence when she took the baby out.

Back then, my best friend was Ban Hua, with white skin and long eyelashes. Later, she got married and had children. She thinks she can have a lovely baby with big eyes. As a result, the child picked out her shortcomings and inherited her husband's small eyes and yellow hair perfectly, which was nothing like her.

My girlfriend joked: "Genes are really powerful! I feel very sorry that I didn't find him a good-looking father, hahaha ... "

As the saying goes, "seven points are doomed to heaven, and three points depend on hard work." In fact, some parts of a child can only be predestined by heaven (genes).

That is the exclusive password of parents, the brand of genes and the "glory" of the family.

I have, you have and he has, so it can be called "pro", "fate" and "virtue".

These three characteristics of children are basically hereditary.

1. Skin color

As the saying goes, "One white covers a hundred ugliness". A fair-skinned child gives people a clean and refreshing feeling at first sight.

In order to produce white fat, many pregnant mothers eat lemons and tomatoes during pregnancy and supplement vitamin C.

There is also a saying in Hunan that pregnant women who eat Chili and soy sauce give birth to black children. For children, favorite peppers and soy sauce are hard to touch.

Who knows, the child born is still not white.

What is the reason?

Nothing, just genes!

What to eat is really useless, because the inheritance of skin color follows the law of "neutralization", which makes people have no choice.

Just like mixed pigments, white+black = gray, oh no, = neither too white nor too black.

If the mother's skin is white, if the father's skin is black, then the child's skin will not be as black as the father, nor will it be as white as the mother.

If the mother's skin is yellow and the father's skin is yellow or even black, then no matter how many tomatoes you eat, it is impossible to give birth to a fair-skinned child (if there is, it must be a mistake).

It's hard. If you want to have a fat child, you have to find a fat husband.

That's right: getting married is not just about finding a husband (wife), but also finding a father (mother) for the children.

2. Hair

Many children are born with little hair and yellow hair. Mothers are worried that their children will always be like this when they grow up, so they shave their full-moon babies, saying that after shaving the fetal hair, the new hair will grow longer and thicker.

But it doesn't really mean anything.

Hair is determined by hair follicles, the number of hair follicles determines the number of hair, and the size of hair follicles determines the thickness of hair. Shaving only removes the finished product of hair follicles and does not change the hair follicles themselves.

A person's hair follicle is basically determined by heredity. From the moment a child is born, his hair follicles will not change. Whether his hair is thick or thin, yellow or black, straight or curly is doomed.

If you want to change your hairstyle, I'm afraid you can only rely on Tony, the barber.

But fortunately, there is one thing that is only passed from men to women, and that is baldness.

Even the British royal family is at a loss, from Prince Philip to Prince Charles to Prince William.

If those hair-growing fruits are really effective, please mail a dozen to Prince William! )

Three generations are doomed to baldness, so that when the fourth generation George Wang Zigang was born, people were already worried about his hairline, hahahahahahaha. ......

Yes, baldness is only passed from men to women.

If the father is bald, 50% will be passed on to his son; Even if my grandfather is bald, there will be a 25% chance to pass it on to my grandson.

In addition, double eyelids, big eyes, big earlobes, long eyelashes and high nose bridge are all dominant genetic characteristics, which may be manifested in children if either parent owns them.

As for the traditional practices such as shaving your head, cutting your eyelashes and pinching your nose, it is tantamount to gilding the lily. Not only is there no scientific basis, but it may also hurt children.

3. Height

Children's height is also the most concerned thing for parents.

To this end, the formula for predicting the height of children is also given online:

Boy height (cm) = (father height+mother height+13)/ 2

Girl height (cm) = (father height+mother height-13)/ 2

And this:

Male height (cm) = (father height+mother height) × 1.08÷2

Female height (cm) = (father height ×0.923+ mother height) ÷2

Are these formulas accurate or not?

Pediatric experts pointed out that the formula for calculating genetic height is obtained after probability distribution and statistical processing, without considering other factors.

Developmental psychology also points out that human height characteristics are influenced by multiple pairs of alleles. Up to now, no one can know exactly how many alleles affect height characteristics, and can't expect to draw a conclusion with a simple formula. It can only be said that an unknown number of genes interact with environmental influences, resulting in extensive individual differences.

The height of a child can still be achieved through hard work.

The so-called "one side of the soil and water supports one side of the people", in addition to heredity, the growth environment also plays a very important role.

However, it is worth noting that the height of children in China generally does not reach the standard value of genetic height.

The Investigation Report on the Current Situation of Children's Height Management in China released in September, 20 17 shows that more than half of the children in China have not reached their genetic height.

The reason is that parents are blindly optimistic about their children's future height expectations, ignore their nutritional environment, fail to plan their children's dietary structure in time, and miss the golden age of their children's height growth.

This also shows the importance of the influence of acquired nutrition on height. Therefore, grasp the two golden periods of children's height growth: 0-5 years old and adolescence, and do these four points well to help children grow taller scientifically.

1. Ensure healthy eating habits

The growth of height mainly depends on the growth and development of bones, so it is necessary to ensure an adequate supply of "raw materials" for bone development.

Eat more foods rich in protein, calcium, phosphorus, magnesium and vitamins, such as a glass of milk and an egg every morning and evening, eat more seafood such as meat, fish and shrimp, and eat more fruits, nuts and grains.

Eat less fried and greasy foods such as hamburgers, pizza and French fries, drink less carbonated drinks, and establish healthy eating habits for children.

2. Ensure adequate outdoor exercise.

Ultraviolet rays in sunlight can promote the synthesis of vitamin D in the body, and vitamin D can promote the absorption of calcium, so outdoor exercise can promote the development of bones and accelerate the growth of bones.

Can consciously guide children to do more high jump, long jump, horizontal bar, basketball, badminton, swimming and other sports. , and ensure at least 1 hour of outdoor sports every day.

adequate sleep

In addition, scientists found that after 10 in the afternoon, it is the peak of human body's secretion of growth hormone, and it will last for a long time. Adequate sleep is an important way to grow taller. It is necessary to help children form the good habit of going to bed early and getting up early to exercise.

4. Keep a happy mood

Depression will reduce the secretion of growth hormone, and children will be criticized and scolded for a long time, which will seriously affect their growth.

If children want to grow taller, parents should reduce anxiety and quarrel, create a warm and happy family environment and create good conditions for their children to grow taller.

Finally, parents should regularly take their children to the hospital for physical examination, monitor their height development and carry out manual intervention as soon as possible. Don't miss the golden age of children's bone development.
