Many hermaphroditic organisms, either plants or animals, are able to reproduce by self-fertilization, at least alternatively with cross fertilization. Theoretical models predict several important consequences linked to this mating system. The first prediction is that a selfing population is less sensitive to inbreeding depression than an outcrossing one, because part of the depression can be « purged » meaning that the recessive deleterious alleles are easier to eliminate by natural selection under selfing. This purge creates a positive feedback to favour self fertilization. In these circumstances, we also expect the evolution of traits facilitating self fertilization (for example closed flowers) and a reallocation of resources from the mal...
