WebOct 13, 2016 · Inbreeding depression, the reduction of fitness caused by inbreeding, is a nearly universal phenomenon that depends on past mutation, selection, and genetic drift. … WebInbreeding 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.
WebInbreeding affected neither immune response nor body size in either workers or haploid males under laboratory conditions. However, fitness characteristics varied significantly among maternal families and colonies.

Selfing leads to progressive homozygosis, which in turn unmasks deleterious recessive mutations and often results in a decline in fitness called inbreeding … WebIn a small population, matings between relatives are common. This inbreeding may lower the population's ability to survive and reproduce, a phenomenon called inbreeding depression.
