WebMore specifically, it measures that part of the total variability of the trait caused by genetic differences among the animals on which the measurements were taken. Heritability, then, is a ratio of genetic variance (V g) to total variance (V p) (i.e., h 2 = V g /V p ). Total variance (or phenotypic variance) includes variance caused by genetic ... Plant breeding is based on phenotyping, not only because of tradition but also because of essence.
