Inbreeding is the process of mating genetically similar organisms. do sagittarius move on quickly Spike Island: Unraveling the mysteries of 'Ireland's Alcatraz'. Contrary to common belief, inbreeding does not in itself alter allele frequencies, but rather increases the relative proportion of homozygotes to heterozygotes; however, because the increased proportion of deleterious homozygotes exposes the allele to natural selection, in the long run its frequency decreases more rapidly in inbred populations. This is associated with the unmasking and elimination of severely deleterious recessive alleles. July 4, 2022 July 4, 2022.
