How parthenogenesis works

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.

NettetIn parthenogenesis the only genome that is used is the female one, either producing a clone of the mother (just by mithosis) or, seldomly, having a crossing over event take place, which doesnt create a clone of the mother (but the only genome that is used to make the offspring is the mother one).
