WebHeritability is a measure of the relative proportion of genetic versus environmental factors that influence the variation of a trait (phenotype). Measures of heritability are classically divided into broad sense ( H2) and narrow sense ( h2) heritability. These are estimated by comparing phenotypic variation between relatives.

WebNarrow-sense heritability was estimated using Allard’s formula (1960), and broad-sense heritability by Mather and Jinks’s formula (1974). These investigations can be used in selection of parental pairs to obtain new varieties. The highest value for narrow-sense heritability in F1 was obtained for the character middle belt leaf area. WebFeb 4, 2013 · ‘narrow sense heritability’ (h 2) is defined as the proportion of trait variance that is due to additive genetic factors ‘broad sense heritability’ (H 2) is defined as the proportion of trait variance that is due to all genetic factors including dominance and gene-gene interactions.
