WebInbreeding occurs when animals are bred to their relatives. The closer the relationship the higher the “inbreeding coefficient”. Inbreeding coefficients measure the degree of inbreeding an animal shows relative to a randomly breeding population. Inbreeding reduces fertility, vigour or overall health and mental stability. WebInbreeding 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 .
