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 … WebIf broad-sense heritability for a trait is very high and narrow-sense heritability is very low, which of the following must be true? Dominance variance must be high relative to total phenotypic variance. Two varieties—X (susceptible) and Y (resistant)—of eggplant were used to characterize the genetics of resistance to a necrotizing plant pathogen.
