Detailed explanation-1: -Somatic Cell Nuclear Transfer Somatic cell nuclear transfer (SCNT), also called nuclear transfer, uses a different approach than artificial embryo twinning, but it produces the same result: an exact genetic copy, or clone, of an individual. This was the method used to create Dolly the Sheep.

Detailed explanation-2: -Then the embryo is implanted into an adult female’s uterus to grow. In 1996, Scottish scientists cloned the first animal, a sheep they named Dolly. She was cloned using an udder cell taken from an adult sheep. Since then, scientists have cloned cows, cats, deer, horses, and rabbits.

Detailed explanation-3: -More narrowly, a clone can be defined as an individual organism that was grown from a single body cell of its parent and that is genetically identical to it.

Detailed explanation-4: -These prohibitions and precautions are based especially on ethical and social reasons, but the underlying reason may be a basic biological one, or even a prejudice: clones are considered to be genetically identical to the individuals to be cloned, and will therefore display the same phenotype.
