Inbreeding is also used to reveal deleterious recessive alleles, which can then be eliminated through assortative breeding or through culling. In plant breeding, inbred lines are used as stocks for the creation of hybrid lines to make use of the effects of heterosis. Inbreeding in plants also occurs naturally in the form of self-pollination.

Individuals within the subpopulation are neighbors in the sense that their gametes may come together and inbreeding within the subpopulation increases homozygosity. Wright's statistical theory for isolation by distance looks at population genetic consequences measured by F-statistics where the correlation of randomly uniting gametes within a ...
The effect of inbreeding in the resulting sub-populations could be studied by measuring the runs of homozygosity in different individuals. [ 4 ] In clinical laboratory testing, the detection of ROH in itself does not indicate a particular genetic disorder but indicates an increased risk of autosomal recessive inherited diseases. [ 5 ]
In clinical genetics, consanguinity is defined as a union between two individuals who are related as second cousins or closer, with the inbreeding coefficient (F) equal or higher than 0.0156, where (F) represents the proportion of genetic loci at which the child of a consanguineous couple might inherit identical gene copies from both parents. [25]
Wright was the inventor/discoverer of the inbreeding coefficient and F-statistics, standard tools in population genetics. He was the chief developer of the mathematical theory of genetic drift , [ 27 ] which is sometimes known as the Sewall Wright effect, [ 29 ] cumulative stochastic changes in gene frequencies that arise from random births ...
Inbreeding depression in Delphinium nelsonii. A. Overall fitness of progeny cohorts and the B. progeny lifespan were all lower when progeny were the result of crosses with pollen taken close to a receptor plant. [1] Inbreeding depression is the reduced biological fitness that has the potential to result from inbreeding (the breeding of related ...
In evolutionary biology and psychology, such an ability is presumed to have evolved for inbreeding avoidance, [1] though animals do not typically avoid inbreeding. [2] An additional adaptive function sometimes posited for kin recognition is a role in kin selection. There is debate over this, since in strict theoretical terms kin recognition is ...
