Narrow versus broad sense heritability

Witryna13 cze 2014 · Narrow-sense heritability is usually more practical than broad-sense heritability because it is easier to calculate and often provides a very good estimate … WitrynaHeritability can be broadly defined as the proportion of phenotypic variability that is attributable to genetic factors; higher estimates suggest that genetic variability has a large influence on the variability of a given trait in the population.

WitrynaNarrow-sense heritability considers additive (not total) genotypic variance. Broad-sense heritability is a measure of the number of genes affecting a trait, while narrow-sense heritability is a measure of the genes with major effects. Narrow-sense heritability assumes there is no environmental influence on phenotype. Witryna31 lip 1997 · Narrow-sense heritability accounts for additive genetic effects only; broad-sense heritability encompasses both additive and non-additive genetic effects.
