Dolly (5 July 1996 – 14 February 2003) was a female Finn-Dorset sheep and the first mammal that was cloned from an adult somatic cell. She was cloned by associates of the Roslin Institute in Scotland, using the process of nuclear transfer from a cell taken from a mammary gland .
In 1996, the institute won international fame when Ian Wilmut, Keith Campbell, and their colleagues created Dolly the sheep, the first mammal to be successfully cloned from an adult cell, at the institute. [13] [14] [15] A year later, two other sheep named Polly and Molly were cloned, each of which contained a human gene.
The first cloned large mammal was a sheep by Steen Willadsen in 1984. However, the cloning was done from early embryonic cells, while the sheep Dolly in 1996 was cloned from an adult cell. [82] Megan and Morag were sheep cloned from differentiated embryonic cells in 1995. Dolly (1996–2003), first cloned mammal from adult somatic cells. She ...

The world's first cloned mammal was born in 1996 at the Roslin Institute just outside Edinburgh.
This can result in a low percentage of successfully reprogrammed cells. For example, in 1996 Dolly the sheep was born after 277 eggs were used for SCNT, which created 29 viable embryos, giving it a measly 0.3% efficiency. [40] Only three of these embryos survived until birth, and only one survived to adulthood. [30]

Furthermore, Dolly was born as an old sheep: By virtue of inheriting a mature set of somatic cell chromosomes, rather than the freshly recombined set of germ-line chromosomes that would accompany natural conception, Dolly began life with shortened telomeres. Thus, Dolly was in a genetic sense 'born old' and lived a shortened life as a result.
