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.
People for which the same situation applies for their 1024 ancestors of ten generations ago would have a coefficient of r = 2 −10 = 0.1%. If follows that the value of r can be given to an accuracy of a few percent if the family tree of both people is known for a depth of five generations, and to an accuracy of a tenth of a percent if the ...

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]
