Five characteristics (hair forms, nasal profile, nostril forms, mongoloid fold and upper eyelid fold) were respectively investigated in six nationalities, including the Buyi, Miao, Shui, Maonan, Dong, and Han nationalities in Southern Guizhou, China. The gene frequencies of five characteristics in the six nationalities were estimated and compared. The results indicated that: (1) for hair forms and nasal profile, the frequency of the dominant gene was lower than that of their recessive gene, but the opposite was true for nostril forms. (2) Among different nationalities, the difference of gene frequency of the mongoloid fold, nasal profile, hair forms and upper eyelid fold was quite significant, which was followed by that of nostril forms. |
