【摘要】：采用PCR扩增及毛细管电泳技术对广西瑶族、苗族人群138名个体进行18个短串联重复序列位点分析。在广西瑶族样本中检出167种等位基因,在广西苗族样本中检出159种等位基因,广西瑶族基因频率分布为0.007~0.579,广西苗族为0.007~0.537,所有基因座基因型频率均符合Hardy-Weinberg平衡(P0.05)。广西瑶族、苗族群体杂合度分别为0.571~0.943和0.603~0.956,个人识别能力为0.767~0.971和0.782~0.968,多态信息总量为0.520~0.890和0.580~0.870;非父排除率分别在0.258~0.884和0.294~0.910,累积个体识别力为0.999 999999 999 999 999 976 02和0.999 999 999 999 999 999 973 38;累积非父排除概率为0.999 999 978 8和0.999 999992 1。
[Abstract]:PCR amplification and capillary electrophoresis were used to analyze 18 short tandem repeats (STR) loci in 138 individuals from Yao and Miao ethnic groups in Guangxi. 167 alleles were detected in the samples of Yao nationality in Guangxi and 159 alleles were detected in the samples of Miao nationality in Guangxi. The frequency distribution of the gene in Guangxi Yao nationality was 0.007 ~ 0.579, and that in the Miao nationality of Guangxi was 0.007 ~ 0.537. The genotype frequency of all loci was in accordance with Hardy-Weinberg equilibrium (P0.05). Guangxi Yao nationality, The heterozygosity of Miao population was 0.943 and 0.6030.56 respectively, the individual recognition ability was 0.7670.971,0.782mm. the total amount of polymorphic information was 0.5200.890 and 0.5800.70.The non-paternal exclusion rate was 0.2580.84 and 0.2940.910, and the cumulative individual recognition ability was 0.999 999999 999 999 976 02 and 0.999 999 999 999 999,389.The total amount of polymorphic information was 0.520 / 0.890 and 0.2940.910 respectively, and the cumulative individual recognition capacity was 0.999 999999 999 999 976 02 and 0.999 999 999 999 9999 389. The non-paternal exclusion probability is 0.999 999 978 8 and 0.999 999992 1.
