WebNov 30, 2024 · The genetic and molecular basis of heterosis has long been studied but without a consensus about mechanism. The opposite effect, inbreeding depression, … WebSelfing leads to progressive homozygosis, which in turn unmasks deleterious recessive mutations and often results in a decline in fitness called inbreeding depression [44]. To survive, an incipient selfing population must rid itself of residual deleterious mutation through a process called purging.

Consider a large non-inbred population with mean fitness W. Then, the size of the population reduces to a new smaller value N (in fact, the effective population size should be used here), leading to a progressive increase of inbreeding. Then inbreeding depression occurs at a rate δ, due to (partially) recessive deleterious alleles that were present at low frequencies at different loci.
