Question

Quizplus · Accepted Answer

Heritability measures the proportion of variation in a trait that is due to variation in genes. It does not measure the specific difference between environmental and genetic influences, or the distribution of phenotypes in a population. Heritability does take into account both environmental and genetic factors, but it specifically measures the contribution of genetic factors to the variation in a trait.
