What information can be inferred if the estimated heritability of a trait is approximately 0.50?
A) The environment must have little to no influence over the expression of the trait.
B) Genes exclusively control the expression of the trait in at least 50% of the population.
C) At least 50% of the variation in the trait in the population is due to genetic differences.
D) The environment completely controls the variation in the trait in the population.

Question

Quizplus · Accepted Answer

A heritability estimate of 0.50 suggests that at least 50% of the variation in the trait in the population can be attributed to genetic differences between individuals. This does not mean that the environment has no influence on the trait, but rather that genetic factors are playing a significant role in determining the phenotype.
