Reproductive cloning

Reproductive cloning was first successfully done with mammals in 1996. The sheep Dolly was the result, an identical copy of her mother.

Process:
 * 1) Egg cell without a nucleus (without the DNA) is combined with the nucleus (DNA) of a cell from another donor.
 * 2) The new cell duplicates and becomes and embryo.
 * 3) The embryo is inserted in a foster mother, who gives birth to the clone of the nucleus donor.
