Inbreeding can arise in populations either as a result of various mechanisms that affect the mating system, or from restrictions in actual or effective population size.
WebInbreeding depression is nearly universal in sexually reproducing organisms that are diploid or have higher ploidies. Impacts of inbreeding are generally greater in species that naturally outbreed than those that inbreed, in stressful than benign environments, and for fitness than peripheral traits.
