Chimerism
Chimerism Definition
Chimerism is a rare disorder wherein chromosomes mix in a single organism. Because of this, a person with chimerism would have two DNA sets, as well as organs that do not match the person's DNA. Chimerism can be exhibited in hermaphrodites, in which the affected organism has both male and female sex organs. This disorder develops during the earliest stages of embryonic growth. Once chimerism forms two non-identical twin embryos merge as one rather than growing separately.
