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 … See more Inbreeding may have both detrimental and beneficial effects.
