Child Intelligence from Mother

From a scientific point of view, there are certain rules to follow when talking about genetic genes. The XY chromosome, whose genetic genes will determine the baby’s IQ and appearance?

Who inherited wisdom to children

Mothers are smart, and most of the children they give birth to are smart.

Intelligence has a certain degree of heritability, and it is also affected by acquired factors such as environment, nutrition, and education. According to the evaluation of scientists, genetic genes account for about 50%-60% of intelligence. In terms of genetic genes, mothers are smart, and most of their children are smart. If they were a boy, they would be smarter.

The reason is that human genetic genes related to intelligence are mainly concentrated on the X chromosome. Females have two X chromosomes and males have only one, so the mother’s intelligence occupies a more important position in heredity.

How baby boys and girls come

First, let’s take a look at how baby boys and girls come

· Boys are XY, X (egg) is from the mother, and Y (sperm) is from the father.

· The girl is XX, X (egg) is from the mother, and X (sperm) is from the father.

Therefore, it is the husband’s fault to give birth to boys and girls. Don’t blame your mother’s belly for failing.

The difference between male and female innate IQ

Boys are XY, so boys’ IQs are all inherited from their mothers, girls are XX, so girls’ IQs are half-influenced by fathers and mothers.

Because girls’ IQ is affected by both father and mother, there will be a neutralizing effect. Therefore, the distribution of girls’ IQ will show a normal distribution, which is inverted-bell shape, with the most in the middle and less on both sides. Then boys are completely affected by only one side, so boys’ IQ distribution will be biased towards two extremes. In other words, there are more male geniuses, but at the same time, there are also a lot of stupid boys.

Who inherited the height to the child

On the premise of balanced nutrition, 70% of the child’s height developability is in the hands of the parents, which means that the parent’s genes are the main factor determining the child’s height, because 35% of the factors that determine the height come from the father and 35%. From mother. If both parents are not tall, it will depend on the baby’s 30% of the acquired efforts.

Who inherited his character to the child

Character is more inherited from father. Although the formation of character has an innate element, it is mainly an acquired influence.

Father’s influence will be greater than mother’s. Among them, the role of father’s love has a greater impact on daughters. A psychologist believes: “The father plays an important role in the formation of the daughter’s sense of self-esteem, identity, and gentle personality.”

Whose appearance has the child inherited

Eye: The shape and size of the eyes of a child are inherited from their parents. If one parent has big eyes, the chance of having a child with big eyes is higher. Double eyelids are dominantly inherited. The baby born with a person with a single eyelid and a person with double eyelids is most likely to have double eyelids. But parents are single eyelids, and generally children are single eyelids

Eyelash: Long eyelashes are also dominantly inherited. As long as one parent has long eyelashes, it is very likely that the child will inherit long eyelashes.

Nose: A large, tall nose and wide nostrils are also dominantly inherited.One of the parents has a straight nose bridge, which is very likely to be passed on to the child. The inheritance of the nose will continue into adulthood. When you are a child, you have a short nose, and you may become a tall nose in adulthood.

Ear: The shape of the ear is inherited. As long as one of the parents has big ears, then the child is very likely to also have big ears.

Obesity: If both parents are obese, will give children a 53% chance of becoming fat people. If one parent is obese, the probability of the child being obese drops to 40%. This shows that about half of fat or not fat can be determined by human factors.

Bald: The Creator seems to favor women, letting baldness pass only to men. For example, if the father is bald, the probability of passing it to his son is 50%. Even the mother’s father will leave the 25% probability of being bald to his grandchildren. This genetic tendency to pass on males to females makes men helpless.
