THE BLOOD GROUPS, SUBGROUPS, AND RH FACTOR OF THE MAPUCHE INDIANS OF THE PROVINCE OF CAUTÍN, CHILE

L. SANDOVAL S., C. HENCKEL and L. GIVOVICH

Abstract

The authors present a sero-anthropological study of 205 Mapuche Indians from Cautín (Chile). There were 86.8 per cent of group O, 8.3 per cent of subgroup A1, 0.5 per cent of subgroup A2, 3.4 per cent of group B, and 1.0 per cent of subgroup AB.

The 3.4 per cent group B in the series may be due to crossing with whites or to the fact that this group was always present in Mapuches even before contact with whites.

The frequency of the standard Rh factor percentage is very high (98.6 per cent) but not 100 per cent as in the data of North American investigators.
