1. A group of cells or organisms that are descended from and genetically identical to a single progenitor, such as a bacterial colony whose members arose from a single original cell.
2. An organism developed asexually from another and genetically identical to it, such as an animal produced from an egg cell into which the nucleus of an adult individual has been transferred.
3. A DNA sequence, such as a gene, that is transferred from one organism to another and replicated by genetic engineering techniques.
4. One that copies or closely resembles another, as in appearance or function: "filled with business-school clones in gray and blue suits" (Michael M. Thomas).
v. cloned, clon·ing, clones
1. To make multiple identical copies of (a DNA sequence).
2. To create or propagate (an organism) from a clone cell: clone a sheep.
