Is height influenced by both environmental and genetic factors?

For most individuals, though, height is controlled largely by a combination of genetic variants that each have more modest effects on height, plus a smaller contribution from environmental factors (such as nutrition). More than 700 such gene variants have been discovered and many more are expected to be identified.

Is height genetic or environmental?

Scientists believe that DNA is responsible for about 80% of a person’s height. This means, for instance, that tall people tend to have children who also grow up to be tall.

Which parent does height come from?
