蒙古族3个群体7项性状的基因频率

Gene Frequency of Seven Traits from Three Mongolian Populations

在内蒙古呼伦贝尔盟调查了蒙古族 3个群体 (巴尔虎人、厄鲁特人和布里亚特人 )的发形、前额发际、上眼睑褶皱、蒙古褶、耳垂类型、鼻梁侧面观、鼻孔类型等 7项性状 ,并计算了基因频率 .结果显示 :上眼睑褶皱、蒙古褶、耳垂类型的显性基因频率高于隐性基因频率 .与兴安盟蒙古族相比 ,呼盟蒙古族鼻梁侧面观、耳垂类型显性基因频率较高 ,另 5项特征显性基因频率较低 .

Seven traits including hair form,hair point of the forehead,eyefold of the upper eyelid,Mongoloid fold,lobe type,nasal profile,nostril form of three Mongolian populations(Bargud,Elute and Buriats)from Hulunbuir league,Inner Mongolia were investigated and their gene frequencies were calculated as well. The results showed that frequencies of the dominant gene of eyefold of the upper eyelid,Mongoloid fold and lobe type are higher than that of recessive gene. Compared with Xingan Mongolian,Hulunbuir Mongolian has a higher dominant gene frequency of nasal profile and lobe type,but,on the contrary,lower dominant gene frequency of other five traits.
