The Sheep Dolly Cloned yet again:

A Cloned Sheep:

Dolly the Sheep, the first mammal successfully cloned from a mature cell, lived only six years. But scientists’ statement that taking similar tissue samples used to clone Dolly to generate four precise genetic reproductions.

Dolly is alive as well as healthy, Nottingham University Professor Keith Campbell, who keeps the Dollies as pets, up-to-date by Genetically these are Dolly. 

Before this, when researchers gave information regarding cloning a sheep in July 1996, only this sheep, Dolly, stayed alive from the 29 embryos produced from 277 eggs. This time, just five embryos were essential to producing each of the Dollies sheep.

The latest experiments, which took place three and a half years ago, became public awareness after Campbell revealed them during a lecture.

Dolly was put down in Feb. 2003 because she was ill with lung disease and arthritis. On the other hand, up to now, the new Dolly quartets are doing well, according to Campbell.
