Question

Quizplus · Accepted Answer

Narrow-sense heritability is defined as the proportion of phenotype variance that is due to additive genetic variance. Broad-sense heritability includes variance due to all genetic factors, including non-additive effects, while multifactorial heritability includes both genetic and environmental factors. Generic and genetic are not terms used to describe heritability.
