Broad-sense heritability (H_b) is the proportion of total phenotypic variance (V_P) that is due to total genetic variance (V_G). It includes all genetic effects: additive, dominance, and epistatic interactions. H_b = (V_G)/(V_P) Narrow-sense heritability (H_N) is the proportion of total phenotypic variance (V_P) that is due to additive genetic variance (V_A). Additive genetic variance refers to the average effect of individual alleles on the phenotype. H_N = (V_A)/(V_P) The key difference is that H_b accounts for all genetic contributions to a trait, while H_N specifically measures the genetic component that can be passed on predictably from parents to offspring, making it more useful for predicting the response to selection in breeding programs.
