What determines the parthenogenetic development of organisms?

Parthenogenesis is virgin reproduction, one of the forms of sexual reproduction of organisms in which female reproductive cells (ova, eggs) develop without fertilization. Thus, parthenogenesis is sexual but unisexual reproduction that occurs during the evolution of dioecious and hermaphroditic forms. The importance of parthenogenesis lies in the possibility of reproduction with rare contacts of heterosexual individuals (for example, on the ecological periphery of the range), as well as in the possibility of a sharp increase in the number of offspring (which is important for species and populations with high cyclic mortality). The emergence of parthenogenesis is facilitated by the distant hybridization of the initial forms, accompanied by an increase in the viability of parthenogenetic forms.
