| Abstract: | In 6 Chinese yak (Bos. Grunniens) populations including 177 yaks, 34 blood protein loci were studied by horizontal starch gel electrophoresis, four of these loci (AKP, ALB, LDH-1, TF) were found to be polymorphic. The percentage of polymorphic loci(P) is 0.118, the mean individual heterozygosity(H) is 0.015, which means a low level of genetic diversity in the whole Chinese yak population. The coefficient of gene differentiation (G
ST
) is 0.0625, which indicated an almost-indistinguishable divergence among different populations at the level of blood protein electrophoresis. |
