I'm not going to say what it is. The new sheep were created by fusing a cell from a foetus to an egg cell. Instead, they will be monitored and scientists will try to duplicate the technique in sheep guaranteed free of the brain-wasting disease.Are you sure you want to delete this comment?

... how was the clone "Polly" different from the first sheep clone named "Dolly"? The difference with Dolly was that it is so much more difficult to clone from an adult cell. PPL's first cloned sheep, Megan and Morag, were announced to the world in 1996.
Polly and Molly, like Dolly the Sheep, were cloned at the Roslin Institute in Edinburgh, Scotland. We would then breed naturally to get the numbers needed for production, both because natural breeding is more effective and we have time to do that while trials are going on. Of course, there are naturally occurring clones in nature, such as in bacteria. Ever heard of Megan and Morag?
