The present paper reports the distribution of blood groups and ABH saliva secretion in two Andhra tribal populations: the Koya Dora and the Konda Kammara. 100 Koya Dora and nearly 110 Konda Kammara adults of both sexes were tested for A1A2BO, MN, Rh (CcDEe) blood groups and ABH saliva secretion. The gene frequencies for A1A2BO, MN and ABH and the gene as well as chromosome frequencies for Rh (CcDEe) systems were calculated. Koya Doras show a higher incidence of A gene than B gene, while the reverse trend is seen in Konda Kammaras. Both the tribes show a high M gene frequency. No Rh(D) negative individual was found in Koya Doras, while 4.59% of Konda Kammaras are Rh(D) negative. The chromosomes CDE, CdE, cDe, cdE, Cde and cde are absent in Koya Doras, while only the four chromosomes CDE, CdE, cDe and cdE are absent in Konda Kammaras. The chromosome CDe shows the highest frequency in both the tribes. The frequency of secretors is, as usual, higher than that of nonsecretors in both the tribes. The intergroup variation between the two tribes is not statistically significant for MN, Rh (CcDEe) and ABH systems, while the difference is significant for the A1A2BO blood groups. Suitable comparisons have also been made with all the other available data from Andhra Pradesh tribal populations with respect to different systems studied. Finally Fi estimates have been calculated after Harpending et al. (1973) and Workman et al. (1974) for Koya Doras and Konda Kammaras to assess their degree of endogamy, considering the codominant systems studied, which suggest that Koya Doras are relatively more isolated than Konda Kammaras.
本文报告了两个安得拉部落群体——科亚多拉人和孔达卡马拉人中血型及ABH唾液分泌情况的分布。对100名科亚多拉成年男女和近110名孔达卡马拉成年男女进行了A1A2BO、MN、Rh（CcDEe）血型及ABH唾液分泌检测。计算了A1A2BO、MN和ABH的基因频率以及Rh（CcDEe）系统的基因和染色体频率。科亚多拉人中A基因的发生率高于B基因，而在孔达卡马拉人中则呈现相反趋势。两个部落的M基因频率都很高。在科亚多拉人中未发现Rh（D）阴性个体，而孔达卡马拉人中有4.59%为Rh（D）阴性。科亚多拉人中不存在CDE、CdE、cDe、cdE、Cde和cde染色体，而孔达卡马拉人中仅不存在CDE、CdE、cDe和cdE这四条染色体。CDe染色体在两个部落中频率最高。与往常一样，两个部落中分泌者的频率高于非分泌者。两个部落之间在MN、Rh（CcDEe）和ABH系统上的组间差异无统计学意义，而在A1A2BO血型上差异显著。还就所研究的不同系统，与安得拉邦部落群体的所有其他可用数据进行了适当比较。最后，根据哈彭丁等人（1973年）和沃克曼等人（1974年）的方法，计算了科亚多拉人和孔达卡马拉人的Fi估计值，以评估他们的近亲结婚程度，考虑到所研究的共显性系统，这表明科亚多拉人比孔达卡马拉人相对更为隔离。
