摘　　要：调查了锡林郭勒盟809例(锡林郭勒蒙古族522例,察哈尔蒙古族287例)蒙古族人9项遗传学指标(内眦褶、上眼睑皱褶、门齿类型、鼻梁类型、鼻孔形状、下颏类型、耳垂、额头发际、头发类型).调查显示:(1)在18个内蒙古人群中,锡盟蒙古族有内眦褶率较低,有上眼睑皱褶率低,铲型门齿率中等偏高,凸鼻梁率较高,宽鼻孔率中等偏低,突型下颏率较高,有耳垂率高,额头发际有尖率高,卷发率高.(2)多数指标未见性别间差异,但是本文两个人群中,男性凸型鼻梁率均高于女性.锡林郭勒蒙古族有上眼睑皱褶率女性高于男性.(3)9项指标间没有明显的相关关系.Nine genetics indexes,including Mongoliod fold,eyefold of the upper eyelid,front tooth type,nasal profile,nostril form,chin projection,lobe type,hair point of the forehead and hair form,were investigated for 809 cases of Mongolian from Xilin Gol league(522 cases from Xilin Gol and 287 from Qahar).The results show that (1)In 18 groups of inner Mongolia people,the Mongolian from Xilin Gol have lower rate of mongoliod fold,lower rate of upper eyelid eyefold,middle and a little higher rate of shovelshaped front tooth,higher rate of umbonate nasal profile,slight lower than middle rate of wide nostril,higher rate of protruding chin,and higher rates of ear lobe,pointed hair point on forehead,and curly hair form.(2)Most of the indexes show no sexual difference.In these two populations,male with wide nasal profile is more than female with the trait.The rate of face with eyefold of the upper eyelid in Xilin Gol Mongolian female is higher than that of male.(3)These 9 indexes show no correlations.
