Hace 5 días · Ian Wilmut (born July 7, 1944, Hampton Lucy, Warwickshire, England—died September 10, 2023) was a British developmental biologist who was the first to use nuclear transfer of differentiated adult cells to generate a mammalian clone, a Finn Dorset sheep named Dolly, born in 1996.
Hace 3 días · It’s the anniversary of the birth of Dolly the sheep, a special sheep whose story changed how we think about cloning and genetics. Back on July 5, 1996, at the Roslin Institute in Scotland, Dolly the sheep came into the world. What made Dolly unique was how she was born.

Carried to term in the womb of another Scottish Blackface ewe, Dolly was a genetic copy of the Finn Dorset ewe.
