From whom does the daughter inherit more genes?

Children all have certain genes, and these genes generally come from their parents. For this reason, many babies look more like their father or mother. Many people believe that if a boy is born, he will look more like the mother, and if a girl is born, she will look more like the father. In fact, whether it is a boy or a girl, it is inherited from both parents and is determined by both parents.

1. Who inherits height more? Half from each parent

Apart from nutritional status, 70% of the initiative of a child's height is in the hands of his parents. The parents' genetics are the main factor determining the child's height, because 35% of the factors that determine height come from the father and 35% from the mother. If both parents are short, then it depends on the baby's 30% acquired efforts.

2. Who inherits more intelligence? Mother

Intelligence is somewhat hereditary, but is also influenced by acquired factors such as environment, nutrition, and education. According to scientists, genetics accounts for about 50%-60% of the influence on intelligence. In terms of genetics, if the mother is smart, the child she gives birth to will mostly be smart. If it is a boy, he will be even smarter. The reason is that the genes related to human intelligence are mainly concentrated on the X chromosome. Women have two X chromosomes and men only have one, so the mother's intelligence plays a more important role in heredity.

To prove this point, let's first review high school biology knowledge: How do boys and girls come about?

Males are XY, with the X (egg) coming from the mother and the Y (sperm) coming from the father.

Girls are XX, X (egg) comes from the mother, and X (sperm) comes from the father.

Therefore, whether the baby is a boy or a girl is the husband’s fault. Don’t blame the mother’s belly for not being able to bear the baby.

Please note that boys are XY, so all of their IQ comes from their mother's genes, and girls are XX, so their IQ is influenced half by their father and half by their mother. Because a girl's IQ is influenced by both her father and mother, there will be a neutralizing effect, so the distribution of girls' IQ will show a natural distribution (normal distribution), that is, an inverted bell shape, with the most in the middle and less on both sides. Then, because boys are completely influenced by only one side, the distribution of boys' IQ will tend to be at two extremes. In other words, there are more geniuses among boys, but at the same time, there are also more idiots among boys.

3. Who do we inherit our personality from more often? Dad

Personality is largely inherited from the father. The formation of personality certainly has innate components, but it is mainly influenced by acquired factors. Comparatively speaking, father's influence is greater than mother's. Among them, the role of fatherly love has a greater impact on daughters. A psychologist believes: "Fathers play an important role in the formation of their daughters' self-esteem, sense of identity and gentle personality." Some experts suggest that fathers can teach their daughters many important lessons and experiences in life, making their daughters' personalities more colorful.
