Parthenogenesis?

  1. Only produces female offspring, though.

  2. Not that I understand it completely - but- according to that reliable authority, Wikipedia, says this:

    The offspring produced by parthenogenesis in
    species that use the XY sex-determination system have two X chromosomes and are female. In species that use the ZW sex-determination system they have either two Z chromosomes (male) or two W chromosomes (non-viable or female), or (theoretically) if clonal parthenogenesis was involved (also called apomixis), they could have one Z and one W chromosome (female).


    Parthenogenesis is also not documented in Mammals, we're not really nit-picking here.
