This chapter deals with the question of what is behind the often misinterpreted term parthenogenesis and what effect it has on marbled crayfish. It starts with a general overview about the mechanisms and genetic consequences of sexual reproductive systems and several different asexual ones. This is followed by a section on the origin of parthenogenesis in animals, its short-term benefits and long-term disadvantages, from the perspective of the evolutionary theory of sex. Then, the current state of knowledge on the extraordinary reproduction mode of marbled crayfish and the presumed cause for its emergence is described. Finally, the possibilities for this crustacean as laboratory animal and its ecological impacts resulting from parthenogenesis are discussed.
