WebBroad-sense heritability (H2) represents the proportion of phenotypic variance that is due to genetic variance. It is calculated by dividing the genetic variance by the phenotypic variance. Narrow- sense heritability (h2)- is equal to the additive genetic variance divided by the phenotypic variance.
