目的 研究浙江畲族人群中DYS2 87和DYS44 0位点的多态性。方法 采用聚合酶链反应扩增DYS2 87和DYS44 0 ,PCR产物用 2 %的琼脂糖电泳分析 10 0名畲族个体的基因型。结果 10 0名个体DYS2 87位点全部是YAP-;没有发现YAP+ ;10名为DYS44 0 3 ,占总人群数的 10 % ,其余 90名是DYS44 0 4。结论 浙江畲族人群DYS2 87和DYS44 0多态性与属于汉藏语系的其它民族之间存在着明显的不同 ,因此这两个基因位点对研究人类的进化是一种稳定的、重要的遗传标记。
Objective To study the polymorphism of DYS2 87 and DYS44 0 in Zhejiang She population. Methods DYS2 87 and DYS44 0 were amplified by polymerase chain reaction (PCR). The genotypes of 100 She individuals were analyzed by 2% agarose gel electrophoresis. RESULTS: All 100 individuals were all YAP-, with no YAP +; 10 were DYS44 0 3, accounting for 10% of the total population, and the other 90 were DYS44 0 4. Conclusion There are obvious differences between DYS2 87 and DYS44 0 polymorphisms in the She ethnic population of Zhejiang Province and other ethnic groups belonging to the Sino-Tibetan language family. Therefore, these two genetic loci are a stable and important inheritance for the study of human evolution mark.
