There are three types of cloning that are mainly used: reproductive, therapeutic and DNA. Cloning is the process of producing a genetically identical organisms that exists in nature.
Reproductive cloning uses a technique called somatic cell nuclear transfer. There are disadvantages to reproductive cloning, such as reduced genetic diversity. Therapeutic cloning is cloning performed for medical uses. Some examples of this type of cloning include using skin to treat burn patients and creating nerve cells. The advantage of therapeutic cloning is that the tissue is generated from the patient's own body and will not be rejected. DNA cloning is used to create plants and micro organisms that have certain desired features.
