本文应用核仁组织区银染技术对正常维吾尔、哈萨克及汉族共90例个体染色体银染形成区(Ag—NOR)频率和近端着丝粒染色体随体联合频率的研究发现:正常堆吾尔、哈萨克群体Ag—NOR、SAc、SAt的值均高于汉族群体(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。 In this study, 90 cases of normal Uygur, Kazakh and Han nationality were investigated by the silver staining technique of nucleolar organizer region. The results showed that the frequencies of Ag-NOR and proximal centromeric chromosomes in 90 normal Uygur, , The values ​​of Ag-NOR, SAc and SAt in Kazakh population were higher than those in Han population (P <0.01), with significant differences. There was no significant difference in frequency among the Uygur and Kazakh populations (P> 0.05), which supported the genetic similarities between the two ethnic groups. This is consistent with the origin of the nation and the ethnographic and anthropological research results of the past.
