Quizplus · Accepted Answer

Narrow sense heritability specifically refers to the fraction of total phenotypic variance that can be attributed to additive genetic factors. Therefore, only the additive effects of alleles are a component of narrow sense heritability. Dominance interactions, environmental effects, and epistatic relationships are not considered in narrow sense heritability.
