Ovis aries (sheep) sheep Lineage: Eukaryota[11549]; Metazoa[5490]; Chordata[2666]; Craniata[2641]; Vertebrata[2641]; Euteleostomi[2619]; Mammalia[718]; Eutheria[544]; Laurasiatheria[302]; Artiodactyla[141]; Ruminantia[94]; Pecora[92]; Bovidae[67]; Caprinae[16]; Ovis[6]; Ovis aries[1]

Ovis aries, the domestic sheep, is an important livestock animal. It is a wool producing animal that has economic importance throughout the world. The genome sequence will facilitate the identification of genes that may provide explanations for the vast range of mammalian variation and help us to better understand the genetic basis of diseases More...common to both human and sheep.
The Ovis aries genome is distributed over 26 autosomes and two sex chromosomes. Less...
