WebThe avoidance of expression of such deleterious recessive alleles caused by inbreeding, via inbreeding avoidance mechanisms, is the main selective reason for outcrossing. Crossbreeding between populations sometimes has positive effects on fitness-related traits, but also sometimes leads to negative effects known as outbreeding depression. WebMany studies on inbreeding avoidance in mammals and birds investigated the role of sex-biased dispersal, avoidance of familiar individuals who have grown up together, and delayed maturation (reviewed in Blouin & Blouin, 1988; Pusey & Wolf, 1996). Furthermore, several experiments under laboratory conditions suggested that animals also avoid ...
