Automixis is a term that covers several reproductive mechanisms.
This reduction in parental legacy has been termed the cost of meiosis (Williams, 1975) and can be avoided by selfing via self-fertilization, the fusion of gametes from the same individual; by automixis, the activation of a meiotically divided cell (see Mogie, 1986); or by apomixis, a process particular to angiosperms and gymnosperms where seeds form without the need of meiosis and fertilization (see Bicknell and Koltunow, 2004).
Thus, in clonal species that can periodically generate new clones to replace those lost through selection (e.g., in parthenogenetic brine shrimps Artemia with automixis; Browne 1992) and can disperse through a heterogeneous environment (Jaenike et al.
