WebHeritability in broad sense (H 2) is calculated using the following formula : H 2 = S g 2 /S p 2 Therefore, H 2 simply gives a measure of the proportion of phenotypic variance which is due to genotype. However, this does not tell us what proportion of an individual's phenotype is due to genotype. Moreover, H 2 depends on the population in which it is measured … WebNarrow sense heritability is a measure of the ratio of additive genetic variation to phenotypic variation in a given population for a given trait.

WebHeritability (h2) is the additive genetic variance divided by the phenotypic variance, (5.1) which essentially quantifies the genetic contribution to the expression of the trait.
