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… WebSep 16, 2016 · However, while inbreeding may not be a good idea for humans, for other species, the practice is not nearly as dangerous.
