WebFeb 26, 2015 · Background Threatened species often have small and isolated populations where mating among relatives can result in inbreeding depression increasing extinction risk. Effective management is hampered by a lack of syntheses summarising the magnitude of, and variation in inbreeding depression. Here we describe the nature and scope of the … WebBoth inbreeding and drift reduce genetic diversity, which has been associated with an increased risk of population extinction, reduced population growth rate, reduced potential for response to environmental change, and decreased disease resistance, which impacts the ability of released individuals to survive and reproduce in the wild.

WebFeb 26, 2024 · Although inbreeding alone does not change allele frequencies, it does redistribute genetic variation, reducing it within families or populations while increasing it among families or populations. Inbreeding also increases selection by exposing deleterious recessive mutations, a process called purging that can deplete genetic variation. WebBecause genetic drift acts more quickly to reduce genetic variation in small populations, undergoing a bottleneck can reduce a population's genetic variation by a lot, even if the bottleneck Genetic drift can cause big losses of genetic variation for small populations.
