摘　　要：报道了广西侗族的ABO、MNSs、Rhesus、Duffy、Kidd、P、Diego、Lewis和Xg等九种红细胞血型系统和ABH唾液分泌型的分布。共调查了201名父母均系侗族而彼此无血缘的学生,其中男116名,女85名。结果表明,广西侗族中ABO系统的r基因(0.6286)、MN系统的m基因(0.6294)、Duffy系统的Fy^a基因(0.9651)、Kidd系统的JK^a基因(0.4628)和Rhesus系统的CDe染色体(0.7532)等频率都很高,ABO系统的q基因(0.1672)、P系统的P_1基因(0.1333)和Lewis系统的Le^a基因(0.3232)等频率较低。MNSs系统的S基因(0.0124)频率很低,而MS染色体连锁率却为零。Xg系统的Xg^a基因频率(0.3746)与汉族和维吾尔族一样,处于低水平。Lewis系统的Le(a+)表型者中发现八例是ABH唾液分泌型,但分泌的物质不是A便是B,而分泌H物质的唾液分泌型者全部都是Le(a-)型。六个民族间遗传距离分析表明,侗族与壮族在血缘上最近,其次是与朝鲜族、蒙古族、汉族相近,而与维吾尔族最远。A total number of 201 unrelated individuals of the Dong nationality in Guangxi are examined for the distribution of ABO, MNSs, Rhesus. Duffy, Kidd, P, Diego, Lewis and Xg blood group systems and ability of ABH secretion. The results show that the gene frequencies fo r (0.63), m(0.63), Fya (0.97), Jka(0.46) and CDe(0.75) are rather high. On the contrary, low gene frequencies of q(0.17), P1(0.13) and Lea(0.32) and very low gene frequency of S(0.01) are observed. Xga gene frequency (0.37) is as low as that of the Han and Uygur nationalities. Among the individuals of Le(a+) pheno-type, only eight ABH secretors are found, who secret either A or B substance but no H substance.The genetic distances between Dong and five other nationalities show that the Dong nationality is genetically closest to Zhuang nationality, and also close to Han, Mongol and Korean nationalities, but has the largetst distance with Uygur nationality.
