Witryna3. The breeder's equation as you wrote it: R = h 2 S. The heritability that is the ratio of additive genetic variance over the total phenotypic variance is called the heritability in the narrow sense and is noted h N 2 = V a V P, where V A and V P are the additive genetic and phenotypic variance respectively. WitrynaHeritability is a statistic used in the fields of breeding and genetics that estimates the degree of variation in a phenotypic trait in a population that is due to genetic variation between individuals in that population.
