维吾尔、哈萨克及汉三民族rRNA基因活性及随体联合的比较研究

STUDIES ON rRNA GENE ACTIVE AND SATELLITE ASSOCIATION IN UIGUR, KAZAK AND HAN NATIONALITIES

应用核仁组织区银染技术对维吾尔、哈萨克及汉族共90人的染色体银染核仁形成区(Ag-Nucleolar Organizing Region,Ag-NOR)频率和近端着丝粒染色体随体联合频率的研究发现:维吾尔、哈萨克群体Ag-NOR及随体联合的细胞数与次数均高于汉族群体(P＜0.01),具有显著性差异。维吾尔、哈萨克群体间上述的频率无显著性差异(P＞0.05),支持了两民族遗传上的相近性。这与民族起源和过去用民族学、人类学研究结果是一致的。

Using techniques of Ag-NOR, the frequencies of Ag-NOR, SAc, SAt of 90 normal individuals of Uigur, Kazak and Han nationalities in Xinjiang Uigur Autonomous Region were studied. The results are summarized briefly in the following.The frequencies of Ag-NOR, SAc, SAt of normal individuals of Uigur, Kazak nationalities are siginificantly higher than that in Han (P<0.01). There is no significant difference between Uigur and Kazak (P>0.05). There is good accordance with the conclusions obtained from human genetical and anthropologcal research.
