Define narrow sense heritability
Webbroad-sense heritability: the widest estimate of the role of genes in influencing total phenotypic variability (see HERITABILITY ), measured by the ratio of total genotypic variance to total phenotypic variance. Compare NARROW-SENSE HERITABILITY . 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 …
