Human cloning is the formation of a hereditarily identical copy of a human, human tissue or human cell.

The moral values of cloning are an extremely contentious issue. Human cloning issue was first addressed by California legislature which banned reproductive cloning. Ever since then Maryland, Indiana, Rhode Island, Michigan, New Jersey, Massachusetts, Iowa, Virginia, North Dakota and South Dakota have enacted actions to forbid reproductive cloning.

There are two types of human cloning: Therapeutic and reproductive cloning. Therapeutic cloning permits scientists to create plentiful source of stem cells for research purposes. In reproductive cloning, the cloned embryo is entrenched in a woman’s uterus, where it potentially results in pregnancy leading to the birth of a cloned human being. Replacement cloning is a third type of cloning involving the combination of both therapeutic and reproductive cloning.
