Scientists Crack the Sheep Genome (image) University of Edinburgh Caption Scientists at the University of Edinburgh's Roslin Institute have helped to crack the genetic code of sheep. The team were part of the International Sheep Genomics Consortium which sequenced the entire genetic make-up of a texel sheep, the same breed shown in this image. Their findings reveal that sheep became a distinct species from goats around 4 million years ago.
