Inbreeding depression is often the result of a population bottleneck. 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. See more Inbreeding depression is the reduced biological fitness which has the potential to result from inbreeding (the breeding of related individuals). Biological fitness refers to an organism's ability to survive and perpetuate its See more Natural selection cannot effectively remove all deleterious recessive genes from a population for several reasons. First, deleterious genes arise constantly through de novo mutation within a population. Second, most offspring will have some … See more Inbreeding may have both detrimental and beneficial effects. The biological effects of inbreeding depression in humans can on occasion be confounded by socioeconomic and … See more • Backward evolution • Genetic diversity • Heterosis (outbreeding enhancement) See more Inbreeding (i.e., breeding between closely related individuals) results in more recessive traits manifesting themselves, as the genomes of pair-mates are more similar. Recessive … See more Hybridization as a conservation effort is be appropriate if the population has lost "substantial genetic variation through genetic drift and the … See more Whilst inbreeding depression has been found to occur in almost all sufficiently studied species, some taxa, most notably some angiosperms, appear to suffer lower fitness costs than … See more WebInbreeding occurs when the alleles at a gene site are identical by descent.
