Resumo
Genetic studies of 540 Paraguayan Indians from nine tribal groups and 51 Mennonites are presented for ABO, MNSs, P1, Rh, Kell, Lewis, Duffy, Diego; for serum immunoglobulins and haptoglobins, G6PD‐deficiency, and thalassemia trait.Group O gene frequencies for all Indian groups were 1.00; for r (cde), 0.00.Tapiete, Lengua, Toba, and Sanapana Rz (CDE) frequencies were among the highest ever reported.N frequencies were high for Ache Kwera (Guayaki), Lengua, Cheroti, Guarayu, Tapiete; N and s low for Ayore. MS frequencies were high for Sanapana, Lengua, Ayore; Ns for Tapiete. Diego was notably absent for Toba, Lengua, Guarayu, Tapiete, Ayore. Homogeneous frequencies for Fya (1.000) occurred among Guarayu and Tapiete, and for P1 among Guayaki. Inv(a) frequencies were low for Cheroti, Chulupi, Guayaki. Hp 1 among Guayaki (Ache Kwera 0.15) is lowest ever reported.G6PD deficiency and abnormal hemoglobins were uniformly absent from all groups.Mennonite results were homogeneous and point toward Dutch origins.Differences among groups studied, and between Paraguayan and other Amerinds emphasize importance of genetic drift and founder principle. Abandonment of their tribes by mixed‐blood offspring is partly responsible for apparent genetic purity and homogeneity of groups.
