Heritability Broadly, heritability is the proportion of variation (more strictly variance) in a phenotypic character in a population that is due to individual differences in genotype. Narrowly, heritability is the proportion of variation (more strictly variance) in a phenotypic character in a population that is due to individual genetic differences that will be inherited by the offspring. There are three possible ways to estimate the heritability of a real character: â¢ One method is to cross two pure lines. (This is mainly of interest in applied genetics, where the problem might be to breed a new variety of crops; it has little interest in evolutionary biology.)
