Another beneficial strategy to increase the maternal inheritance of Wolbachia is to induce the production of female offspring without fertilization by sperm, a process known as parthenogenesis (thelytoky).

Conduct library research to learn more about at least three of the following: parthenogenesis, apomixis, gynogenesis, pseudogamy, facultative parthenogenesis, cyclical parthenogenesis, heterogony, thelytoky, arrhenotoky, parthenocarpy, and apomictic parthenogenesis.
According to the mode of sex determination, parthenogenesis is classified in: arrhenotoky (unfertilized eggs develop into males, fertilized ones into females), deuterotoky (unfertilized eggs develop into either sex), and thelytoky (unfertilized eggs develop into females) (Mittwoch 1978, de Meeus et al.

Although most unisexual animals are invertebrates, detailed investigations on the evolutionary genetics of thelytoky have concerned mainly vertebrates.
For detection of thelytoky caused by Wolbachia infection, specific primers for DNA amplification of the wsp region of Wolbachia were used: wsp-Forward primer 5'TGGTCCAATAAGTGATGAAGAAAC-3' and wsp-Reverse 5' -AAAAATTAAACGCTACTC CA-3' (Braig et al., 1998).
Thelytoky in hymenopteran parasitoids is often the result of infection with intracellular endosymbionts, especially the bacterium Wolbachia pipientis (Rickettsiales: Rickettsiaceae) (Werren et al.
