      Hmmm… Chimeras are an organsim composed of two separate populations of cells (derived from two distict orgnaisms/individuals) ….

      check out the subtitle "Parasitic twin" at this url: http://en.wikipedia.org/wiki/Fraternal_twins

      yes it’s possible –> chimeras are the already called examples, but there are numerous mosaics in this world (namely all the females). They have populations of cells expressing different chromosomes.

      There was actualy a very good
      documentary about this.

      These people were suposed to be one of twins
      but the other twin and them fused together
      at cellular division.. Some babies are unfortunate
      to be born both male and female and both light
      and darker skin. (bilaterally)
      And there was profiled the case of a woman who
      had her children taken a way because blood tests
      revealed her dna did not match her children.
      However with chimeras dna from other twin would
      be found from a different source such as internal organs.

      Very facinating!!
