WebAn understanding of the genetic structure of inbreeding species derives from the combining analyses of theoretical models with studies on experimental and natural populations. Inbreeding can arise in populations either as a result of various mechanisms that affect the mating system, or from restrictions in actual or effective population size. 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…
