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.
Without pedigree collapse, a person's ancestor tree is a binary tree, formed by the person, the parents (2), the grandparents (4), great-grandparents (8), and so on.. However, the number of individuals in such a tree grows exponentially and will eventually become impossibl

Wright introduced the inbreeding coefficient F as the correlation between uniting gametes in 1922, and most of the subsequent theory of inbreeding has been developed from his work. The definition of the inbreeding coefficient now most widely used is mathematically equivalent to that of Wright. [7]
In 1984, one of the children, a 14-year-old girl, revealed the details of a long history of torture and abuse (physical, sexual, and psychological) to a school official. As the case was investigated, authorities learned that a number of Goler children were victims of sexual abuse at the hands of fathers, mothers, uncles, aunts, sisters ...
The term coefficient of relationship was defined by Sewall Wright in 1922, and was derived from his definition of the coefficient of inbreeding of 1921. The measure is most commonly used in genetics and genealogy. A coefficient of inbreeding can be calculated for an individual, and is typically one-half the coefficient of relationship between ...
Endogamy is the cultural practice of mating within a specific social group, religious denomination, caste, or ethnic group, rejecting any from outside of the group or belief structure as unsuitable for marriage or other close personal relationships.
