What proportion of a person’s height is genetic?

Information: The adult height of children who grow up in a good living environment depends largely on genetics.

According to statistics, 70% to 75% of the human body's adult height depends on genetic factors, and only 25% to 30% depends on environmental conditions such as nutrition and exercise.

Generally, when the parents are tall, the children are also tall; when the parents are short, the children are also short.

Shanghai Medical University used the height median value (that is, the sum of 1/2 of the parents' height) to conduct a correlation analysis with the children's height at each age. It was found that the correlation between the height of parents and their children increased with age, suggesting that the more genetic factors are in

The closer to the mature stage of the individual, the more fully it is expressed. This phenomenon is called family aggregation of growth and development.

Accordingly, the adult height of children can be predicted based on the mid-parental value, combined with the height, age and bone age of the child at that time.

----It has been observed that the proportion of children born to short-statured parents who are taller than their parents is relatively large, while the proportion of children born to tall-statured parents is relatively small.

----In real life, we often see some parents with short stature, but their children are not short.

Some parents who are tall have children who are not tall.
