Human cloning. Computer artwork of a human army of clones. Clones are genetically identical copies of an individual, engineered from a genetic sample of that individual. It is theoretically possible to use cloning to produce unlimited genetic copies of someone. Cloning could also be used to make copies of a template that is genetically engineered for improved health, strength and intelligence. The highlighted clone (white) could represent the loss of individuality or the original individual from which this army was cloned.
