　　【Blood Protein Type Analysis】

　　Main Analyzing Institutions and Completion Time: College of Agriculture and Animal Husbandry, Qinghai University, 2001. Zhang Caijun and Wang Yong used polyacrylamide gel electrophoresis to study the polymorphism of serum esterase in 211 Yushu horses. The results showed that: (1) the polymorphism of serum esterase in the examined Yushu horses was controlled by three alleles: ESF, ESL, and ESs, with Es being the dominant allele (0.500); (2) the gene heterozygosity at the serum esterase locus was 0.5520, and the genetic differentiation coefficient among populations was very small (0.33%); Blood Protein Type: ES type

　　Whether Correlation Analysis Was Conducted: Yes.

　　Main Analyzing Institutions and Completion Time: Institute of Animal Science, Chinese Academy of Agricultural Sciences, Beijing. YH. Ling, YH. Ma, WJ. Guan et al. Evaluation of the Genetic Diversity and Population Structure of Chinese Indigenous Horse Breeds Using 27 Microsatellite Markers. Animal Genetics, 2011, 42（1）：56-65。

　　Analysis Results: Mean Number of Alleles (MNA): 8.41, Effective Number of Alleles (NEA): 4.57, Locus Richness (AR): 7.58, Heterozygosity (H): 0.764, Observed Heterozygosity (Ho): 0.724, Inbreeding Coefficient (FIS): 0.052.
