Cloned dinosaur. Conceptual computer illustration of a cloned Velociraptor dinosaur and a cloned foetus in beakers on a shelf with genetics books. A clone is a genetically identical copy of an organism. Cloning involves taking the genetic material from the cell you wish to clone and implanting it into an egg cell (ovum) from which the genetic material has been stripped.
