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 genetic material. Inbreeding depression is often the result of a population bottleneck.

WebFeb 4, 2024 · Inbreeding is more likely to occur in small populations simply because there is a greater chance that an individual will mate with a relative. In a diploid species, inbreeding increases the likelihood that an individual will have two alleles that are identical by descent at any given locus, and it therefore has the effect of increasing homozygosity at all loci.
