Does the child's height, appearance and IQ follow the father or the mother?

Have a son with your father and a daughter with your mother. I wonder if everyone thinks so? There seems to be no clear conclusion about whose genes the child inherited. So does the child's height, appearance and IQ follow his father or his mother?

1, height

The height of a child is a matter of great concern to everyone. There is a proverb in the countryside called "My father is my mother and my mother is my nest." So, the mother has a greater influence on the height of the child? Actually, it's not. According to scientific research, almost all babies' height is influenced by their parents, which does not mean that one side has a much greater influence on children's height than the other.

In fact, even if parents are not tall, children can improve their height through parenting. For example, paying attention to cultivating children from various angles such as sleep, exercise and diet can make him break through the height of his parents.

Here is a way to predict your child's future height: generally speaking, if you grow taller in the future, your baby's arms and legs will be very long. From a scientific point of view, this is because the bones in these two positions belong to long bones, which will grow synchronously with the height, so that the height of the child can be predicted.

Step 2 show up

In fact, appearance is a relatively broad issue. It is not a specific organ, but refers to the feeling that the child's whole face gives to others. Some people think that children are like fathers, while others think that children are like mothers. In fact, children's facial features are all autosomal inheritance, and the average baby will have the characteristics of father and mother.

For example, if mom and dad are both single eyelids, then the baby must be single eyelids; If mom and dad have double eyelids, the baby only has the possibility of116 with a single eyelid. Just kidding, if the father is bald, then the son born is more likely to be bald; On the contrary, if it is a daughter, it is not so easy to go bald. This is because related genes exist in sex chromosomes.

3. IQ

I believe that everyone is most concerned about the baby's IQ. In fact, the acquired factors influenced by the educational environment and the innate factors of children have similar effects on children's IQ. In other words, the influence of parents only accounts for about 50% of children's intellectual development.

As for whether a child's IQ is greatly influenced by his father or his mother, the answer is actually his mother. Because IQ-related genes are generally located on the X chromosome of autosomal and sex chromosomes, if a boy is born and his father does not provide the X chromosome, it is naturally less influenced by his father.

Of course, children can also improve their IQ through training the day after tomorrow.
