As the heritability index for a particular behavior decreases:

B)the rate of DNA methylation decreases.
C)epigenetics plays less of a factor as a determinant of gene expression.
D)genes explain less of the individual differences in that behavioral trait.

Question

Quizplus · Accepted Answer

The heritability index represents the proportion of individual differences in a trait that are attributable to genetic differences. As the heritability index decreases, genes explain less of the individual differences in that behavioral trait. This does not necessarily mean that nature becomes more important than nurture or that epigenetics plays a lesser role in gene expression, although these factors may still contribute to individual differences in the behavior.
