Here is the specifics from that page: ...."Recently, the Komodo dragon, which normally reproduces sexually, was found also to be able to reproduce asexually by parthenogenesis. .... Because the genetics of sex determination in Komodo Dragons uses the WZ system (where WZ is female, ZZ is male, and WW is inviable) the offspring of this process will be ZZ (male) or WW (inviable), with no WZ females being born. ..... A case has been documented of a Komodo Dragon switching back to sexual reproduction after a known parthenogenetic event. .....It has been postulated that this gives an advantage to colonization of islands, where a single female could theoretically have male offspring asexually, then switch to sexual reproduction with them to maintain higher level of genetic diversity than asexual reproduction alone can generate.".... --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Cosmology, Mathematics and Philosophy" group.
