(Photograph) - Dollying up: Fleece from the world's first cloned sheep is to be spun into yarn by Leeds University's school of textile industries and then used to make the first "cloned" woollen jumper. The jumper will be sold to help raise funds for the Cystic Fibrosis Trust. Scientists at the Roslin Institute in Edinburgh, Dolly's home, donated the fleece to the trust because the research surrounding her creation may provide the key to a cure for cystic fibrosis. The jumper made of the fleece, displayed by Leeds textile technologist Barry Greenwood, will be presented to the Science Museum in London next month.
