There are potential benefits in certain types of cloning. One type is called asexual reproduction, which is the cloning of plants. And Reproductive cloning which involves the cloning of humans and human organs.
Gardeners and horticulturists have known the benefits of cloning for years. They use cloning in a process called vegetative propagation. Also known as plant cutting, a section of a living plant is cut away. This section is then placed in a medium like soil or water, and often treated with hormones.In many cases, roots will then grow from the cutting, and a viable, genetically identical new plant is the result. Some benefits of cloning in this way are that especially resistant plant lines can be reproduced for use in diseased areas, individual plants can be shared between gardeners, and reproducing plants that have an offensive sex can be avoided.
The reproductive cloning of animals occurs when an egg without a nucleus is successfully combined with a cell from a donor. This sort of cloning has already occurred, but is not expected to have a high rate of success for many years. Some benefits of cloning in this way are that extinct and near-extinct species could be reproduced for zoos and/or reintroduction into the wild; highly prized domesticated animals could be duplicated to improve food yields in the dairy, beef, pork, and poultry industries; a new pet with a similar genetic potential to a loved one that is lost could be created; and winning race animals could be cloned for competition.
Reproductive cloning is also theoretically possible in humans. The benefits of cloning humans, however, can change with the moral stance of the people discussing the subject. Using reproductive cloning, a couple unable to conceive children could have cloned eggs of each-other implanted into the female. The clones would have the potential to be born just like normal children, and could be raised just as normal children are....
