贵州苗族、水族5项群体遗传学特征的研究

Five population genetic traits of Miao and Shui nationalities in Guizhou Province

对贵州苗族、水族人群共913人(苗族448人,水族465人)的叠舌、卷舌、前额发际、耳耵聍和足趾长5项群体遗传学特征进行了调查.结果显示:两民族叠舌、卷舌、前额发际和耵聍4项群体遗传学特征存在显著性差异(P<0.05或P<0.01),足趾长差异不明显(P>0.05);两民族性别间前额发际差异极显著(P<0.01),苗族男女间卷舌差异明显(P<0.01);5项群体遗传学特征间相关性不大;贵州苗族与水族遗传距离较远.

Samples of 913 cases （Miao Nationality 448 and Shui Nationality 465） were investigated on 5 genetical traits（curly top of tongue, curly sides of tongue, front form of hair, cerumen and plantar digital formular） of Miao and Shui nationalities in December 2007 in Guizhou Province. The results showed as follows. There are significant difference（P〈0. 05 or P〈0. 01）on 4 characters（curly top of tongue, curly sides of tongue, front form of hair, cerumen）, and significant sexual difference（P 〈0.01） on front form of hair in two nationalities, and only significant sexual diffefence （P〈0. 01） on curly sides of tongue in Miao Nationality. There are few corelations on 5 population genetical traits, and more far on genetical distance between Miao and Shui nationalities in Guizhou Province.
