Chimerism really sounds like something formed out of a Nigerian name. Are you sure it wasn't discovered by some Igbo dude named Chimere or Chime:)

But seriously when one considers the things that could go wrong in the system of an organism, and how none of them goes wrong for a long long time, you just can't help be grateful for the blessings, seen and unseen.

Now, a question, do you think it is possible to isolate the cells with one type of DNA and gradually extract them from the body until it is only one set of DNA that is left? And if that is possible, what becomes of the blue eye in the case of the chimera cat? Does it gradually turn hazel or it just remains the same? Too many questions, I know.
