A chimera is a living plant or animal that is composed of genetically different types of tissues joined by virtue of grafting, fused embryos or mutation. A chimera may also occur through the manipulation of genetically different types of DNA in a lab. The word chimera is derived from a beast in Ancient Greek mythology that had a lion head, a goat body, a serpent tail and breathed fire. When referring to this specific animal, Chimera is capitalized, as it is a proper name. Today, chimera may refer to any animal or plant that is a mixture of different types of animals or plants, mythical or actual. With the advent of research into genetically modified organisms or GMOs, the word chimera is coming into wider use. Related words are chimerism, chimeric, chimerical, chimerically.
