The studies on the genetic diversity of the phenotypes and its distributions, chromosomal patterns and bands, isoenzymes, mtDNAs and genomic DNAs of Tibetan sheep are systematically reviewed. The result shows that the studies are so preliminary that the Tibet sheep抯 origin and differention is difficulty to discuss. So it is necessary to improve the researches of Tibet sheep by different methods, especially on the DNA抯 level.
