Cloning is the doubling of a human or animal.
That made the baby sheep identical to the mother Dolly. Many scientists say cloning can help and improve the trasformation of the insulin gene by providing blood for those who need it, creating organs needed by a person in case of an accident. Also, if there are clones people would send their clone to work instead of them, and they would spend more time with their family. There are many advantages of cloning because they could find a way to treat diseases and study them further by duplicating the disease. It can also be used to replace bad organs.
