WebThe response to selection depends of the heritability of the trait: R = h2 N S (see figure 9.6 pg. 237). An important consequence of this is that as selection proceeds, the additive genetic variation will be reduced ("low" alleles removed). As the V A decreases, the heritability decreases (see equation for heritability above). WebBroad sense heritability describes the ratio of total genetic variance to phenotypic variance as discussed above. Narrow sense heritability describes the ratio of additive genetic variance to phenotypic variance. Genetic evaluation calculations use estimates of additive genetic variances.
