In 1996, Ian Wilmut and his colleagues at the Roslin­ Institute in Edinburgh, Scotland, successfully cloned a sheep named Dolly.

•Scientists used an udder cell from a six-year-old Finn Dorset white sheep.

•Then they injected the cell into an unfertilised egg cell (which was taken from a scottish blackface ewe),had its nucleus removed, and made the cells fuse by using electrical pulses.

•The scientists cultured the fused cells for six or seven days to see if it divided and developed normally, before implanting it into a surrogate mother, another Scottish Blackface ewe.

•The implantation was successful and dolly was cloned successfully.
