WebInbreeding depression is important in the evolution of outcrossing mating systems and, because intercrossing inbred strains improves yield (heterosis), which is important in crop … WebInbreeding is the mating of individuals related by ancestry. It is measured as the probability that two alleles at a locus are identical by descent (F). Inbreeding increases homozygosity and exposes rare alleles. When parents of an individual share one or more common ancestors (i.e. are related), the individual is inbred.

In general, the higher the genetic variation or gene pool within a breeding population, the less likely it is to suffer from inbreeding depression, though inbreeding and outbreeding depression can simultaneously occur.

WebAug 9, 2024 · 1. Introduction. Inbreeding depression occurs when matings between relatives result in decreased offspring fitness. This reduction in fitness is likely due to an increase in homozygosity that exposes deleterious recessive alleles to selection [].This phenomenon has been observed across many taxa [2,3], but the degree to which an individual … WebInbreeding depression is caused by increased homozygosity of individuals, as shown in Fig. 1. There are two genetically distinct ways in which increased homozygosity can lower fitness:...

WebInbreeding depression may potentially be reduced, or purged, by breeding related individuals. However, the Speke's gazelle example, often cited as a demonstration of reduction of inbreeding depression, appears to be the result of a temporal change in fitness in inbred individuals and not a reduction in inbreeding depression.
