Wilmut's team in February 1997 at the Roslin Institute. The process involved fusing an adult sheep's cell nucleus with egg cells, leading to ethical debates surrounding cloning. Dolly's lineage was verified through DNA fingerprinting, ensuring no natural mating occurred with her surrogate. The exact reasons for the cloning success are still unclear, but may relate to the properties of the cultured cells used.
