The northern part of the owls' range has seen more consistent declines in demographic rates, and it has a longer history of invasion by barred owls. This type of isolation may result in the formation of race or even speciation, as the inbreeding first removes many deleterious genes, and permits the expression of genes that allow a population to adapt to an ecosystem.

Fixation of alleles most likely occurs through Muller's ratchet, when an asexual population's genome accumulates deleterious mutations that are irreversible. However, in species such as horses, animals in wild or feral conditions often drive off the young of both sexes, thought to be a mechanism by which the species instinctively avoids some of the genetic consequences of inbreeding.

[65] By pairing chromosomes of similar genomes, the chance for these recessive alleles to pair and become homozygous greatly increases, leading to offspring with autosomal recessive disorders. [2] By analogy, the term is used in human reproduction, but more commonly refers to the genetic disorders and other consequences that may arise from expression of deleterious or recessive traits resulting from incestuous sexual relationships and consanguinity. [55] While linebreeding is less likely to cause problems in the first generation than does inbreeding, over time, linebreeding can reduce the genetic diversity of a population and cause problems related to a too-small gene pool that may include an increased prevalence of genetic disorders and inbreeding depression.

The high incidence of cystic fibrosis (CF) in most European populations (and populations of European descent) can be explained by different hypotheses that can be tested using the available data concerning this disorder. What we found in Munster for example is that theres not one member with Munster ancestry outside of the province. Cavalleri said that over the centuries, when you remove emigration, people would largely have stayed within provincial boundaries for much of their lives. 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. The gorillas were even more inbred than they expected, roughly the equivalent of the result of a mating between great-uncle and great-niece, they found. Inbreeding depression can also occur in a large population if individuals tend to mate with their relatives, instead of mating randomly.
