Research Progress on Genetic Diversity and Origin of Cattle,Sheep and Cervidae
Absrtact:Cattle,sheep and cervidae resources are precious wealth of mankind,they can not only provide mankind with rich products such as meat and milk,but also have irreplaceable value in medicine and scientific research.However,these genetic resources are being lost and some varieties have become endangered or even extinct.A comprehensive understanding of the population status,genetic variation,and dif-ferentiation as well as the identification of ancestral types and migration routes can be achieved through the exploration of their genetic di-versity and origin.Scientific conservation and breeding programs can be proposed to provide a scientific basis for the protection of genetic resources.In this study,the research methods of genetic diversity of cattle,sheep and cervidae and the research progress of paternal and ma-ternal origins were reviewed,which provided a reference for the protection of germplasm resources and endangered species and the devel-opment and utilization of genetic resources.
