"Daughters are like dads, sons are like moms"!
In fact, the inheritance of genes is really magical and interesting, especially newborn children, always carry the characteristics of two parents.
Come and see what good genes your children have inherited from you?
The child's skin is not white,
Mom and Dad multiply and take the average
Skin color is inherited between 63% and 72%.
If the parents are both "yellow-skinned" or not very white, the child will most likely not be too white.
The parents are black and white, and the child may be in the middle or may be biased towards one side.
Mom and Dad are very white, and the child's skin will most likely be very white.
Barack Obama, the 44th president of the United States, has dark skin and his mother is white.
After Obama was born, his skin color was close to brown, that is, "white + black = chocolate"!
However, most parents want their children to be clean, especially little girls.
If you are born with yellow skin or even wheat skin color, then don't expect to be white to glow, but you can drink more water, keep sleep, strengthen metabolism and improve the condition of the skin.
Is baldness inherited?
What many mothers are most afraid of is that the baby inherits her father's "Mediterranean"!
As long as there is hair, it is easy to say, find a good Tony teacher, the child is not a problem to look good, afraid that there is no hair to toss.
Will it be inherited in the end!
The answer is: Yes!
But having a daughter can basically be relieved, because baldness is mostly passed on from man to woman, and if you have a son...
Some scientists have found that:
The fact that more men are bald than women is related to androgen levels. Baldness is also not controlled by a single gene, and there is no question of whether the baldness gene is dominant or recessive.
Therefore, the anecdotal saying that "baldness is dominant in baby boys and hidden in baby girls" is questionable.
Most myopia,
It's all done by the children themselves
Many myopic parents are most worried,
It is that their children wear glasses at a young age.
Most studies have shown that myopia is genetically predisposed, especially highly myopic, but the way and causes myopia are inherited are complex.
One of the most widely circulated sayings is:
If both parents are nearsighted, the risk of myopia is 4 times higher than if neither parent is nearsighted.
Playing games, not going out..., these are the real culprits that really lead to glasses at a young age.
So parents don't have to blame themselves too much.
Is the child's IQ high or not to look at the mother?
Have you ever heard a proverb like this:
Daddy is stupid, mother is stupid.
It sounds ridiculous, but it makes sense.
Some studies believe that intelligence genes are more inclined to be inherited from the mother.
Because human genes associated with intelligence are mainly concentrated on the X chromosome. Women have 2 X chromosomes and males have only 1, so the mother's intelligence occupies a more important place in heredity.
After studying junior high school biology, we will know:
Boys are XY, X (eggs) are from the mother, and Y (sperm) is from the father.
Girls are XX, X (eggs) are from the mother, and X (sperm) is from the father.
Boys have only one X, which means that boys' IQ is inherited from their mothers; while girls have two X's, so their father and mother each have half the influence.
In addition, the research results of Yale University in the United States and Newcastle University in the United Kingdom said:
The children raised by the father have high IQs, good grades, and a high career success rate.
Fathers have a big influence on their children's IQ, and this influence can last even until the age of 42.
Good character is inherited from Dad?
One psychologist argues that:
Fathers play an important role in the formation of their daughters' sense of self-esteem, identity and gentle personality.
The real reasons for "personality like dad" are:
When parents get along, fathers can teach their daughters more important lessons and experiences in life, and every word and deed of the father is the object of children's learning and imitation, so the children will become more and more like fathers.
What determines the final character of the child is the influence from the family, the words and deeds from the parents, and the harmonious atmosphere from the family.
With a grumpy and moody father, the child will not be inherited to have a good and gentle personality, but will only become angry and angry.
Parents are humble, then the child will be polite in the world.
Determine the height of the child
It's not just genetics
Whether heredity affects the height of the child is also a matter of great concern to parents.
A person's height is actually affected by "congenital genetics + acquired intervention", of which congenital inheritance accounts for 80% and acquired intervention accounts for 20%.
The currently widely accepted way to calculate height is as follows:
Adult lifetime height (cm) for boys = (father height + mother height + 13) / 2 + - 7.5 (cm)
Adult lifetime height (cm) for girls = (father height + mother height -13) / 2 + - 7.5 (cm)
Among them, "+-7.5cm" is actually an acquired intervention, which can affect as many as 15cm.
If dad's height is 170cm and mom's height is 160cm, in theory:
The son is between 164 cm and 179 cm tall and the daughter is between 151 cm and 166 cm.
Many parents are worried that their sons are not tall, in fact, as long as the acquired intervention, such as children play more basketball and more sports, do not always hide at home, it is still very helpful for the long body.
1. Ensure adequate sleep
After the child goes to sleep, especially after 10 pm, the growth hormone secretion is vigorous and lasts for a long time, which is very conducive to growing tall.
2, enough outdoor exercise
Ultraviolet rays in sunlight can promote vitamin D synthesis in the body, and vitamin D can promote calcium absorption, so outdoor exercise can promote bone development, and children can naturally grow taller.
3. Healthy eating habits
Eat more foods rich in protein, calcium, phosphorus, magnesium and vitamins, milk, eggs, meat, fish and shrimp, fruits, nuts, boneless, etc. are suitable for eating more.
