摘　　要：目的探讨广西壮、苗族人5项人类遗传学经典指标的规律。方法对聚居于广西的1046名壮、苗族学生进行调查。结果(1)广西壮、苗族R型扣手、R型交叉臂和R型惯用手百分率,民族间差异均无显著性(P>0.05):扣手和交叉臂与性别无关;(2)广西壮族环指长和直型拇指类型百分率均高于苗族,差异有显著性或高度显著性(P<0.05或P<0.001);(3)苗族男性环指长百分率高于女性,壮族女性直型拇指类型百分率高于男性(P<0.05)。结论广西壮、苗族人扣手、交手臂、惯用手、环食指长和拇指类型有其规律性。Objective To explore the rule of 5 general index of anthropotogical genetics of Zhuang and Miao nationalities of Guangxi. Methods A group of l046 individuals were studied for 5 general indexs of anthropological genetics of Zhuang and Miao nationalities of Gnangxi. Results (1)There were no significant diffe rancies inthe frequency of R hand clasping,R arm folding and R handedness in 2 nationalities,hand clasping and arm folding no relation with sex.(2)The frequency of long type of ring finger and type of straight pollical type in Zhuang nationalities were higher than that in Miao nationalities of Guangxi(P< 0.05 ,P< 0.001,respectively).(3)The frequency of long tyqe of ring finger in male was higher than that in female in Miao nationalities,and the frequency of type of straight pellical type in female was higher than that in mate in Zhuang nationalities(P< 0.05). Conclusion Hand clasping,arm folding,handedness,palmar digital formula,and pollical type in Zhuang and Miao nationalities of Guangxi have rule.
