Is there a genetic basis for head size?

The size of the head circumference has a certain relationship with genetics, and if the parents have a large head, the child's head may also be large. There are certain individual differences in the size of the skull, from person to person. But this difference does not determine whether a person is smart or stupid.

It is said that the brain of the nineteenth-century Russian writer Turgenev weighed 2,102 grams, while the brain of the ** family Frances weighed only 1,017 grams, which is almost twice the difference, but can you say which of them is smart and which is stupid?

Therefore, there is no scientific basis for the claim that a big head is smart. Whether a person is smart or not has nothing to do with the size of the skull, but the size and structure of the brain in the skull, and more importantly, the development of the acquired ones.

And if the head is very large, it may also be a manifestation of certain diseases, such as the head of a child with rickets is not only large and square, but also has a soft skull; Children with hydrocephalus and megaencephaly have a larger head circumference than normal children, and their brain weight is also more, and their motor development is delayed, mental retardation, and sometimes convulsions. In addition, there are many factors that affect the child's intelligence, and if the mother abuses drugs during pregnancy, suffers from rubella, and has unbalanced nutrition, it will directly affect the child's acquired intelligence. In addition, whether the child's upbringing is appropriate, whether the child is diligent, etc., will directly affect the child's "genius".

I haven't heard of it, so there should be no genetic factor.

Summary. Hello, you can change it.

The head of the fetus is not necessarily small, the size of the head circumference will not be inherited, as long as the pregnant woman eats more nutritious food during pregnancy, the fetus will absorb the natural head circumference will be larger.

My mother's head is the same size as mine, and this genetics can be changed.

Hello, you can change it.

As long as the pregnant woman eats more nutritious food during pregnancy, the fetus will absorb the natural head and the head will be large.

<>Now that I'm 17 years old, I still have a chance to make my head bigger.

At this age, the head shape is basically fixed, and it will basically not change again.

It's nice to have a small head, but it looks petite.

My head is a little too small.

As long as there are no other uncomfortable problems, the size is fine, don't worry too much, <>
