ABSTRACT
In order to assess the genetic variability and population structure of north-east Asian cattle, 13 microsatellite loci were analysed for a total of 200 individuals including Korean, Chinese, Japanese Black and European Holstein cattle. Observed and expected heterozygosity, two estimators (F(ST) and G(ST)) of gene differentiation, and Nei's DA distance were evaluated. Based on expected mean heterozygosity, the lowest genetic diversity was exhibited in Japanese Black cattle (H(E)=0.471), and the highest in Chinese cattle (H(E)=0.744). Korean cattle revealed a relatively high degree of genetic diversity (H(E)=0.728). Average proportion of genetic variation because of interpopulation subdivision among north-east Asian cattle varied between 10.9 and 9.9%, depending on the estimator used. N-J tree based on Nei's DA genetic distance showed that Korean and Chinese cattle are closely related, whereas Japanese Black cattle are clearly distinct from the other two populations, forming a north-east Asian outgroup.
