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.
Maria Antonia had the highest coefficient of inbreeding in the House of Habsburg, 0.3053: [6] her father was her mother's maternal uncle and paternal first cousin once removed, and her maternal grandparents were also uncle and niece. Her coefficient was higher than that of a child born to a parent and offspring, or brother and sister.
Globally, 8.5% of children have consanguineous parents, and 20% of the human population live in communities practicing endogamy. [ 3 ] [ 4 ] Theories on the developments of consanguineous marriage as a taboo can be supported as being both a social, and a biological development.
Conversely, significant rates of modern human gene flow into Neanderthals occurred—of the three examined lineages—for only the Altai Neanderthal (0.1–2.1%), suggesting that modern human gene flow into Neanderthals mainly took place after the separation of the Altai Neanderthals from the El Sidrón and Vindija Neanderthals that occurred ...

The coefficient of relationship is sometimes used to express degrees of kinship in numeric terms in human genealogy. In human relationships, the value of the coefficient of relationship is usually calculated based on the knowledge of a full family tree extending to a comparatively small number of generations, perhaps of the order of three or four.
