Inbreeding genetic defects in humans
WebEpidemiologic studies usually measure inbreeding effects in terms of genetic load, which is not readily translatable into morbidity and mortality. Several methods of computing … Inbreeding increases homozygosity, which can increase the chances of the expression of deleterious or beneficial recessive alleles and therefore has the potential to either decrease or increase the fitness of the offspring. With continuous inbreeding, genetic variation is lost and homozygosity is increased, enabling the expression of recessive deleterious alleles in homozygotes. The c…
