In a variety of settings—additive epistasis in a diploid, dominance in an autotetraploids, shared environmental effects (such as epigenetic contributions), maternal effects, and dominance under inbreeding—the response in the mean has both a permanent and a transient component. The latter arises because selection perturbs the population distribution of genotypes away from their Hardy-Weinberg values. Upon the cessation of selection, any change in allele frequencies remains, but any additional changes due to departures from Hardy-Weinberg decay away. The result is that, even in the presence of these transient components, the breeder's equation often accurately predicts the amount of permanent response.
