摘要: The purpose of this study was to assess genetic diversity, phylogenetic relationship and population structure among nine Eurasian cattle populations using 58 single nucleotide polymorphism (SNP) markers. calculated distribution minor allele frequencies heterozygosities suggested that the diversity Bos indicus lower than taurus populations. Phylogenetic analyses revealed main divergence between populations, subsequently Asian European By principal components analysis, were clearly distinguished with PC1 (61.1%); however, six clustered loosely partial separation groups observed by PC2 (12.5%). analysis performed STRUCTURE program. Distinct shown at K = 2, 3. At 4, 5 6, Mongolian showed an admixture pattern different ancestry cattle. 7, all each cluster little proportion admixture. In conclusion, SNP markers in could sufficiently estimate for especially STRUCTURE.
