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. This … WebThe issue with inbreeding is that it can reveal harmful recessive traits that would usually not be expressed (especially not lots of them together) in more outbred individuals. However, since individuals with a lot of these harmful traits tend to die or not reproduce and not all inbred individuals will end up with the recessive alleles because ...

Homozygosis of low penetrance tumor genes, and its frequency in the population, can increase or decrease the risk of cancer [1,2,3,4,5,6]. WebClose inbreeding leads to homozygosis and, as a rule, to a decline in fit-ness. The latter-inbreeding depression-results in part from the expres-sion of deleterious recessive mutations that ordinarily are concealed by more nearly normal, dominant alleles.
