What happened to Dolly’s clone?

Why was Dolly cloned?
Making Dolly Dolly was part of a series of experiments at The Roslin Institute that were trying to develop a better method for producing genetically modified livestock. If successful, this would mean fewer animals would need to be used in future experiments.
What does it mean when someone is cloned?
Human cloning is the creation of a genetically identical copy (or clone) of a human. The term is generally used to refer to artificial human cloning, which is the reproduction of human cells and tissue. It does not refer to the natural conception and delivery of identical twins.

three mothers
Well, actually, Dolly had three mothers. One mother gave Dolly her DNA, one mother supplied an egg, and the third mother, her surrogate mother, gave birth to her. Normally, an animal gets half of its DNA from its mother and half from its father.
What happened to Dolly the first cloned sheep?
Dolly died on February 14, 2003, at age six from a lung infection common among animals who are not given access to the outdoors.
