贵州南部6个民族5对遗传性状的基因频率

对贵州南部地区布依族、苗族、水族、侗族、毛南族和汉族5对遗传性状的基因频率进行了研究，并对民族间基因频率差异进行显著性检验。结果显示：（1）发型和鼻梁侧面观的显性基因频率均明显低于隐性基因频率，而鼻孔形状则相反。（2）内眦褶、鼻梁侧面观、发型和上眼睑皱褶的基因频率在民族间差异较大，而鼻孔形状则较小。

Gene Frequency of 5 Genetic Characters in 6 Nationalities in Southern Guizhou

The gene frequency of 5 characters was reported in Buyi,Miao,Shui,Maonan,Dong,and Han nationalities in southern Guizhou,and analyzed for statistical significance among these nationalities.The results showed that:(1) For Hair forms and Nasal profile,the frequency of the dominant gene was lower than that of theirs recessive gene,but the opposite was true for Nostril forms.(2)Among different nationalities,the difference of gene frequency of Mongoloid fold,Nasal profile,Hair forms and Eye fold of the upper eyelid was quite significant,which was followed by that of Nostril forms.
