NettetThe reason parthenogenesis results in Males in the komodo dragon and females in whiptails has to do with sex chromosomes and sexual determination, and not the mechanism of parthenogenesis. In the komodo dragon, animal with two identical sex chromosomes (in this case ZZ) is male, a female is ZW and WW is non-viable. Parthenogenesis can occur without meiosis through mitotic oogenesis. This is called apomictic parthenogenesis. Mature egg cells are produced by mitotic divisions, and these cells directly develop into embryos. In flowering plants, cells of the gametophyte can undergo this process. The offspring produced by apomictic parthenogenesis are full clones of their mother. Examples include aphids.
