摘要

Variations of four sheep populations in China were examined by multiloci electrophoresis, and similar data are quoted to analyze the degree of genetic differentiation of native sheep populations in East and South Asia. Among 15 populations, the average heterozygosity is 0.2746, and the effective number of alleles is 1.559. Mongolian sheep possess the highest genetic diversity, and diversity decreases sequentially in the Chinese, Vietnamese, Bangladeshi, and Nepalese populations. Coefficients of genetic differentiation are 0.0126–0.3083, with an average of 0.148, demonstrating that the major genetic variation (85%) exists within populations. Genetic identity and genetic distance all show relatively low genetic differentiation. No relationship was found between geographic distance and genetic distance. Gene flow is common among the mass of populations, which leads to the inconsistency between geographic distance and genetic distance. The 15 native sheep populations in East and South Asia can be divided into two groups, one group including part of the Chinese and Mongolian populations and another including theYunnan population of China and part of the Nepalese and Bangladeshi populations. Other populations did not separate into groups, merging instead into the two main groups.
