Human cloning creates a direct duplicate, not a twin. Reproductive cloning copies an existing gene to create a clone. This form of asexual reproduction has come under ethical criticism as some claim it is science playing God. However, there are some advocates of reproductive cloning that believe it is beneficial for humans and animals.
Arguments in support of this scientific procedure claim that infertile couples may benefit from reproductive cloning. Couples who cannot conceive naturally turn to fertility treatments and other procedures for help. Some couples who can produce eggs and sperm are able to conceive this way. However, reproductive cloning provides another option for those who want children but cannot produce eggs or sperm. The process of reproductive cloning can create a genetically related child for the couple, according to The Center for Genetics and Society. The child produced by cloning would be the genetic duplicate of one of the parents.
Those in support of reproductive cloning argue that it would allow homosexual couples to have a genetically related child. Lesbian couples would be able to have a child without using a donor sperm. Gay men would also benefit from the procedure because they would not need an egg. However, a surrogate mother would still be necessary to carry the pregnancy. Arguments supporting reproductive cloning say it would give the option of parenthood to non-traditional couples.
Humans may not be the only beneficiaries of reproductive cloning. Endangered species may benefit from cloning as well. Animals like the African elephant, blue whale, snow leopard and giant panda are nearing extinction. Reproductive cloning may give these animals the chance to thrive again by creating duplicates for breeding. In 1996, the cloning of Dolly the sheep in Scotland became the first successful attempt at cloning from an adult cell. This scientific breakthrough opened the door for the possibility of helping endangered species.
