Red blood cells of 255 inhabitants of San Antonio Palopo, an Indian community on the eastern shore of Lake Atitlán, Guatemala, have been typed with antiserum.. to Diego a (Di(a)) and the newly discovered antiserum to Di(b). Individuals with erythrocyte antigenic types Di(a+ b-, Di(a+ b+), and Di(a-b+) have been found, but the type Di(a-b-) has not been encountered. Population frequencies of antigenic types and family studies support the hypothesis that the erythrocyte antigens, Die and Dib, are controlled by two codominant alleles at a single autosomal locus.
对危地马拉阿蒂特兰湖东岸的一个印第安社区圣安东尼奥-帕洛波的255名居民的红细胞，用抗血清对迭戈a（Di(a)）和新发现的抗Di(b)抗血清进行了分型。已发现具有红细胞抗原类型Di(a+b-)、Di(a+b+)和Di(a-b+)的个体，但未遇到Di(a-b-)类型。抗原类型的群体频率和家系研究支持这样的假说，即红细胞抗原Di(a)和Di(b)由常染色体上单一基因座的两个共显性等位基因控制。
