Cloning

1. An egg cell was removed from the ovary of an adult sheep B The egg cell's nucleus is then removed. 
2. Nucleus from the organ cell, for example udder cell, of adult sheep A is the taken out and inserted into the empty egg cell. 
3. The fused cell has complete set of chromosome and began to develop normally (in the lab) using genetic information from the donated DNA. 
4. Before the dividing cells specialize, the embryo is implanted into the uterus of a surrogate mother sheep C. The offspring is genetically identical to sheep A.
