Dolly sheep

First mammal cloned from an adult somatic cell but she was not the first ever cloned mammal, another sheep before was cloned from an embryo cell (1984  in Cambridge, UK). 

Dolly was a genetic copy of the Finn Dorset ewe. She had three mothers: one provided the egg, another the DNA, and a third carried the cloned embryo to term.  

She was named after the country singer Dolly Parton

Female Finnish Dorset sheep, she spent her normal life at The Roslin Institute. Over the years she had a total of six lambs with a Welsh Mountain ram called David. 

After discovering tumours growing in her lungs, Dolly was put to sleep on 14th February 2003, at the age of six.

Dolly's body was preserved and donated by the Roslin Institute in Scotland to the National Museum of Scotland  in Edinburgh.
