WebFor example, inbreeding increases the proportions of homozygotes, and the most extreme form of inbreeding, self-fertilization, eventually eliminates all heterozygotes. Inbreeding and outbreeding are evolutionary strategies adopted by … WebFeb 26, 2024 · Inbreeding also increases selection by exposing deleterious recessive mutations, a process called purging that can deplete genetic variation. For all these reasons, inbreeding is a central concept in evolutionary biology. Inbreeding is also central to conservation biology as small and isolated populations become prone to inbreeding and …
