Broad- and narrow-sense heritabilities

WebOct 24, 2024 · While broad- and narrow-sense heritabilities are variable across conditions, we also observed that on average, most of the phenotypic variance can be explained by additive effects (mean h 2 = 0.55). However, non-additive components contribute significantly to some traits, explaining on average one third of the phenotypic … WebBroad-sense heritability, defined as H 2 = V G /V P, captures the proportion of phenotypic variation due to genetic values that may include effects due to dominance and epistasis.
