Height depends on dad, IQ depends on mom? Who is in charge of the genetics of the couple?

Who does the child look like? I don’t know if the child will be tall or not, whether the child is smart or not, etc. On the topic of genetic inheritance, many mothers and fathers are controversial.

I remember one time I took my child to play with a friend. I said that it was not good for a child to eat too much sugar because I didn't let the child eat too much sugar. Then the child argued with us about our age.

Then a mother in the car was surprised: "Your child is so tall at this age, look at those big legs, tusk..."

Then the mother said: "My child is one year older than you guys. I am anxious looking at the short legs."

We looked at this baby mother who was over 1.6 meters tall and had a good body, so we told her: "It's okay. The child will grow up. Do you think you have long legs? Don't worry."

Mother: "But the child's father has short legs. I am worried that the child will inherit his father."

On the issue of the height of a child, some people say that boys follow their fathers and girls follow their mothers. In terms of children's appearance, they say that boys look like mothers and girls look like fathers.

Who is in charge of the child's height?

Not long ago, there was an internet celebrity who quickly became popular because of his height of 1.88 meters.

A girl so tall, many netizens are curious: "How do you grow so tall?"

"What do you eat?"

"Is there any secret?_Strong14strong

Then the girl uploaded a photo of her family portrait: "Actually, there is no secret, but the gene is strong, haha. ”_Strong14strong

The tallest brother in the photo is 1.96 meters, and the older brother is 1.94 meters, and her grandmother, the lowest in the family, is also 1.75 meters tall.

So the child is not tall , Still depends on genetic inheritance.

Research shows that: in the inheritance of height, parents and family inherit 70%, and the other 30% can be cultivated, such as usual living habits, surrounding environment and oneself Sports and so on.

I remember a piece of news that their parents are not tall, but their sons are tall. This is how they grew up.

His father is only 1.6 meters tall and his mother is 1.68 meters tall. And because his son has practiced swimming since he was 6 years old, he is now 1.94 meters tall.

so everyone often says "Dad frustrated one, mother frustrated." 's statement is unreliable Yes, the height of a child is not the mother’s own pot, so ladies, we don’t remember this pot!

Who determines the child’s IQ?

After talking about height, let’s talk about IQ again. No parent does not want their children Smart, but who is the child’s IQ? Everyone is constantly arguing about this.

I remember an expert said: "If you have a smart husband, then you have to be careful, don't Underestimated your mother-in-law! ”_Span65span

means,Boys’ IQs are easily affected by their mothers’ IQs. If their mothers’ IQs are high, then boys’ IQs are highly likely to be high.

Because the x chromosome of a boy basically comes from the mother, and most of the genes that determine IQ are present on the x chromosome, it is a girl, and both parents have equal influence on her.

Who did the child look after?

After talking about IQ, let’s talk about looks and looks. Many people say "Boys look like mothers, girls look like fathers." This phenomenon does exist in most families.

Take the cute babies in the entertainment industry, such as Jia Nailiang and Tianxin :

There are also some who look like mothers, such as Qi Wei and daughter Li Leqi: _pimg pstrongp _p2

is like skin tone , if both parents have white skin,The chance of a child's natural white skin is very high; if the parents are black and white, the child's skin color is more likely to be a combination of both sides, which is whiter than black and slightly darker than white.

Then there are eyes and nose . If both parents have big eyes and high nose bridge, then the child will have a very high appearance in the future; if both parents have big eyes and small eyes, then the child will grow To one side.

There is also hair, like those people who have hair loss and baldness in middle age, most of them are men, and the baldness gene is only passed on from male to female, so the gender of the child is The essential.

Of course, dominant inheritance and figure, like those born with a slender figure, then their parents' figure will not be much worse, if both parents are obese, the child is very big The odds are a little fat guy.

For girls, like the pear-shaped body and the apple-shaped body, this is a proper dominant inheritance. If the mother has a pear-shaped body, it is difficult to reduce the thick legs of the daughter; if the mother has an apple-shaped body, then the daughter’s upper body Obesity is also difficult to lose.
