Inbred mutations

WebSince inbreeding increases the probability of being homozygous, it increases the fraction of the potential deleterious effect that is expressed and, therefore, exposed to selection. This causes some increase in the selective pressure against (partially) recessive deleterious alleles, which is known as purging. Typical coancestries between relatives are as follows: Father/daughter or mother/son → 25% ( 1⁄4) Brother/sister → 25% ( 1⁄4) Grandfather/granddaughter or grandmother/grandson → 12.5% ( 1⁄8) Half-brother/half-sister, Double cousins → 12.5% ( 1⁄8) Uncle/niece or aunt/nephew → 12.5% ( 1⁄8) ...
