To study the short teadem repeat(STR) genetics structure of a Chinese Yunnan Yi racial group.
Genetic distributions for nine STR loci were determined based on STR gene scan marked by fluorescence.
Sixty-nine alleles and 164 kinds of genotypes were detected and identified from 84 unrelated Yi racial individuals. The corresponding gene and genotype frequencies were in 0.0060-0.5060 or 0.0119-0.4167 respectively. The expected and observed genotype frequencies of nine STR loci were in accordance with the Hardy-Weinberg equilibrium(P>0.05). The statistical analyses of nine STR loci showed that PIC was distributed in 0.5804-0.8777, H was in 0.6507-0.8002, DP was in 0.7976-0.9558, EPP was in 0.5207-0.8386, except TPOX and THO1 loci.
Above research data enrich the Chinese genetic database, and play an important role in Chinese genetic study and in forensic application.
研究中国云南彝族人群的短串联重复序列（STR）遗传结构。
基于荧光标记的STR基因扫描确定9个STR位点的基因分布。
从84名无血缘关系的彝族个体中检测并鉴定出69个等位基因和164种基因型。相应的基因频率和基因型频率分别在0.0060 - 0.5060和0.0119 - 0.4167之间。9个STR位点的预期基因型频率和观察到的基因型频率符合哈迪 - 温伯格平衡（P>0.05）。对9个STR位点的统计分析表明，除TPOX和THO1位点外，PIC分布在0.5804 - 0.8777，H在0.6507 - 0.8002，DP在0.7976 - 0.9558，EPP在0.5207 - 0.8386。
上述研究数据丰富了中国遗传数据库，在中国遗传学研究和法医学应用中发挥重要作用。
