Ten cattle populations, 3 Asian (Hanwoo, Yanbian, Wagyu), 2 African, and 2 European Bos taurus as well as 2 Asian B. indicus and one Bali cattle, B. banteng, were characterized with 13 microsatellite markers. A total of 364 animals from the different cattle populations were used in the study. Allele frequencies were used to estimate expected heterozygosities (He), genetic distances (Ds), and to perform principal component analysis. 165 alleles were observed across all loci. The data supported a common origin for the Hanwoo and Yanbian cattle (Ds=0.013). No evidence for a major West European taurine introgression into the Wagyu was observed. The Eastern Asian cattle were found to be genetically distinct from the European and African taurine and from the Asian zebu. It is recommended that the genetic uniqueness of these cattle breeds be maintained in conservation and improvement programmes.
