 Dolly was the first mammal to be brought into the world using SCNT. Ian Wilmut and his team at the Roslin Institute in Scotland replaced the nucleus from an oocyte taken from a Blackface ewe with the nucleus of a cell from the mammary gland of a six-year old Finn Dorset sheep (these sheep have a white face). They transferred the resulting embryo into the uterus of a surrogate ewe and approximately five months later Dolly was born. Dolly had a white face: she was genetically identical to the Finn Dorset ewe from which the somatic cell had been obtained.
