摘要
目的了解云南蒙古族头面部群体遗传学特征。方法采用随机整群抽样法调查云南省通海县208例(男性105例,女性103例)蒙古族9项头面部群体遗传学指标。结果 1)云南蒙古族有内眦褶率89.5%,上眼睑皱褶率91.4%,铲型门齿率96.19%,凸鼻梁率32.4%,宽鼻孔率80%,突型下颏率32.4%,耳垂率76.2%,额头发际有尖率21%,卷发率7.7%;2)除了耳垂类型和鼻梁类型外,其余7项指标类型出现率在性别间均无显著性差异;3)9项特征彼此间相关性极小;4)与内蒙古9个蒙古族人群相比,多存在极显著差异。结论云南蒙古族与北方内蒙古蒙古族群体差异较大。
Objective To understand the genetic characters of Mongolian＇s head face. Methods Nine genetics in- dexes were investigated for 208 middle schol students（ 105 males and 103 females） in Mongolian nationality by u- sing cluster random samplingrnethod. Results 1 ） The rate of Mongolia fold is 89.5 %, the rate of eye fold of the upper eyelid is 91.4%, the rate of shovel-shaped front tooth type is 96. 19%, the rate of umbonate nasal profile is 32. 4% , the rate of wide nostril is 80% , the rate of protrudingchin is 32.4% , the rates ofear lobe is 76. 2%, the rate ofpointed hairpointon forehead is 21% and the rate of curly hair form is 7.7% inMongolian nationality; 2） No significant sexual diffrernce was found in the frequencies correlations. Condnsions There are differences between Mongolia area. of 7 genetics indexes; 3）These nine indexes showed no Mongolian nationality and the Mongolian groups in Inner
