Cloning is a form of asexual reproduction which involves creating genetically identical genes or cells, plants or animals. The procedure of cloning is done by taking a gene from the animal or human and then putting that gene in another animals or human organisms. Scientists found out that cloning can also make identical twins by using a method called embryo splitting.
In July 1996, a team of Scottish scientists had the first cloning success. Dolly was the first ever cloned sheep. Therapeutic cloning is practiced to clone things such as organs and tissues for patients in need of them. Reproductive cloning is practiced for the purpose of actually producing a human that is genetically identical to somebody else. Human cloning is the creation of a genetically identical copy of an existing, or previously existing human, by growing cloned tissues from that individual. The term is generally used to refer to artificial human cloning; human clones in the form of identical twins are commonplace. Human cloning is amongst the most controversial forms of practice. One of the most ethically questionable problems with human cloning is farming of organs from clones. (Pence, 1998)
