WebAug 25, 2015 · Narrow sense heritability (h 2) is defined as the additive variance divided by the phenotypic variance: h 2 = σ 2A /σ 2P, with the additive variance being the variance of the average effects of the alleles, representing the genetic component of variance responsible for parent-offspring resemblance. h 2 is directly linked to the expected genetic … WebApr 11, 2024 · However, lower narrow sense heritability indicated that additive effects were low.
