Inbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically.

WebPlant breeders can use self-pollination as a type of inbreeding, creating plants that are genetically more identical and that produce identical offspring after many generations. Crossbreeding This is often used to produce offspring with desirable characteristics from two different individuals. WebJan 1, 2024 · Inbreeding in plants often occurs naturally in the form of self-pollination (Richards 1986). A breeding system was then developed to avoid the expression of deleterious alleles caused by inbreeding procedures – such a technique is referred to as outbreeding (or outcrossing; e.g., Bernstein et al. 1985 ).

WebThis inbreeding may lower the population's ability to survive and reproduce, a phenomenon called inbreeding depression.
