WebInbreeding is one of the three major traditional breeding programmes that breeders have used for centuries to improve animals and plants. While it is not as important as selection or crossbreeding, inbreeding is used to produce genetically improved livestock, plants, and laboratory animals. WebInbreeding is also used to produce test animals that will be used in various experiments. 4. Producing outstanding individuals Even when used improperly and when inbreeding depression does occur, inbreeding can still produce good offspring. The depressions seen for various phenotypes are population means. Outstanding
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. Inbreeding can significantly influence gene expression which can prevent inbreeding depression.

WebA strain’s degree of inbreeding is designated by the letter F followed by the number of generations of filial breeding (e.g., F20). Heterozygosity can be completely eliminated by F60 (Herbert III, 2012).
