There are two motives for cloning humans : to produce offspring (reproductive cloning) and for biomedical research (therapeutic cloning). In therapeutic cloning, the embryos can only undergo a few cycles of cell division and cannot develop into a few grown baby. These embryos are never implanted into a womb and never go into the fetal stage. Therefore, this type of cloning is justifiable and is considered ethical. However, there are many people who object the reproductive cloning.
Some people may want reproductive cloning because of the following reasons:
1. Parents want to replace their lost child.
2. If one parent has a harmful gene that he/she does not want to pass to the next generation, cloning can prevent the child from inheriting this bad gene. In some cases, parents may want their children to have certain traits that can be given to an embryo through cloning.
3. Infertile couples could have a baby.
4. Gay couples can produce offspring.
5. A person with traits that could potentially help the society improve could be cloned. For example a clone of Albert Einstein.
Why therapeutic cloning is useful:
1.provides knowledge about the human development
2.help discover new therapies to cure genetic diseases by inserting a specific gene into an embryo.
3. help scientists advance and learn how to cure many disorders and diseases.
4. Cloned embryos are predicted to have a large source of embryonic stem cells that can help repair damaged tissues and organs.
