Which of the following statements BEST reflects the extent to which we can distinguish the effects of genes and the environment on the expression of a complex trait?

A. If one individual is 60 inches tall and another is 70 inches tall, they differ in about 80% of their genes.

B. None of answer options is correct.

C. For identical twins raised in the same environment, height should not differ by more than 20%.

D. In a group of individuals of the same sex, about 80% of the variation in height among individuals is due to genetic differences and 20% is due to environmental differences.

E. About 80% of an individual's height is determined by genes and 20% by environment.

Option D. In a group of individuals of the same sex, about 80% of the variation in height among individuals is due to genetic differences and 20% is due to environmental differences.

Explanation:

Because genetic variations are more common and prominent as traits flows from one generation to next generation while environmental difference are just only exist in that particular environment.
