You measure the narrow-sense heritability of two behavioral traits. For trait A, heritability is 0.1. For trait B, it is 0.6. For both traits, phenotypic variation is identical. Which of the following can be concluded from these data?

A) The variance due to interactive effects is higher for trait B.
B) The variance due to dominance effects is higher for trait A.
C) The variance due to additive effects is higher for trait B.
D) The variance due to genetic effects is lower for trait A.
E) The variance due to epistatic effects is higher for trait B.
