Abstract: For years the research on domestic animal diversity has emphasized diversity of economic traits, ecological diversity and diversity of breeds. Recently, research on genetic diversity of domestic animals has  developed rapidly.  Research on clusters of breeds, systematic conservation, the relationships between genetic diversity and economic traits, and ecological diversity has all made great progress, including some success with QTL, and creating transgenic and cloned animals. The genetic analysis between domestic breeds and their wild relatives was applied to breeding new strains or breeds by hybridization.Evaluation methods using biotechnology have confirmed that many local breeds are unique to China,and this has given rise to worldwide interest.
