Web1.1.2 Inbreeding. Inbreeding is defined as the probability of two alleles in an individual being identical by descent, and is normally the result of mating related individuals. The rate of inbreeding is a function of the characteristics of the foundation stock as well as limited population sizes in subsequent generations (Falconer, 1989 ). WebApr 9, 2024 · Without widespread inbreeding, any one-off cases would primarily affect individual deer rather than the overall population in a given area. Because inbreeding hasn’t historically been an issue among wild whitetails, not much is done at the state or property level to prevent it from happening.
WebInbreeding is the mating of closely related individuals. Inbreeding causes a decrease in heterozygosity and an increase in homozygosity.
