Does a daughter inherit her IQ from her father or mother?

The inheritance of a daughter's IQ is related to her congenital genetic factors, and acquired factors can also affect the IQ of the fetus, so it is necessary to conduct an examination to know which aspect of the child's IQ is inherited. A daughter's IQ may be inherited from her father or her mother. The genes for intelligence are mainly on the X chromosome. Both men and women have X chromosomes, so there is a certain probability of inheritance.

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 for this 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.

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.

So 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: Boys are XY, so all of their IQ is inherited from their mothers; girls are XX, so their IQ is influenced half by their father and half by their mothers.

Because a girl's IQ is influenced by both her father and mother, there will be a neutralizing effect. Therefore, the distribution of girls' IQ will show a normal distribution, which 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 tends to be biased towards two extremes. In other words, there are more geniuses among boys, but at the same time, there are also more idiots among boys.
