First cloned animal was

Dolly sheep was born on July 5, 1996, through the technique of somatic cell nuclear transfer. It includes the transfer of cell nucleus from an adult cell into an unfertilized, enucleated oocyte (developing egg cell). Electric shock is given to the hybrid cell to stimulate it to divide and the resulting blastocyst is implanted in a surrogate mother. Dolly was the first clone produced from a cell of an adult mammal. Polly and Molly's sheep have also cloned animals produced by somatic cell nuclear transfer but they were cloned after Dolly (in 1997).
