This article is one of millions ideas that are coming out everyday and all I can do is take it all in as best as I can. The way I know how to do that is to step by step analyze and incorporate what I already know. They were both carried full term by a surrogate mother. These sheep were not produced from the fertilization of a female egg and a male sperm. The mature ewe, Dolly, is the first mammal to be cloned from an adult.
Cloning involves the use of two cells, an unfertilized egg, the recipient.
The other cell, the donor, is the one being copied. In these specific experiments the cells went through special measures to make the donor and recipient compatible. The cloning of Dolly was successful and repeatable. Dolly looked like the expected breed of sheep that donated the original genetic information. She is indeed the clone of an adult.
