If heritability of a character is very high e.g., 0.8 or more, selection for the character should be fairly easy because there would be a close correspondence between genotype and phenotype.
WebMay 11, 2024 · Calculating Heritability. Broad-sense heritability is represented as H 2 and indicates all the genetic factors that go into phenotypic variance in a population.

WebUnder an additive model (narrow-sense heritability), the parent-offspring correlation would suggest heritability of no more than 2*.10 = 20%, the avuncular would suggest 4*.07 = … WebPhenotypic correlation is function of genetic and environmental correlation. The expression can be simplified by substituting the square root of variances as suggested by Walsh. h2 = 2 A / 2 P 2 A = h 2 2 P A = h P The square root of additive genetic variance (A) is the product of square root of heritability (h) and the square root of ...
