http://hawaiireedlab.com/gwiki/index.php?title=Heritability 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.

Web- heritability does not indicate the degree to which a characteristic is genetically determined - an individual does not have heritability - there is no universal heritability for a characteristic - even when heritability is high, environmental factors may influence a characteristic - heritabilities indicate nothing about the nature of population differences in a characteristic 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.
