GH:  You're kidding.... how "identical" is identical, as far as
     mice are concerned?  Do you mean "EXACTLY genetically identical"?

     Also, there are "parthogenetic" animals who asexually
     reproduce, so that are all genetically identical.
     Small animals, some annelids, flatworms, aphids, and
     I've heard, some large animals like fish and lizards
     reproduce asexually and form genetically identical
     schools, tribes, families etc. Is this true?
