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). 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.
