Regression Toward the Mean in Height
Why might a child whose parents are both over six feet tall grow to be under six feet tall?
A
The variation in heritability is low, which prevents the child from inheriting the parents' extreme height.
B
Environmental factors reduced the child's height, and the child inherited genes for average height from their extended family.
C
The principle of regression toward the mean suggests that when parents exhibit an extreme trait, their offspring will tend to be closer to the population average.
D
The child inherited more genetic traits for height from their average-height grandparents than from their parents.
