This paper reports the distribution of blood groups, A‐B‐H secretors, haptoglobins, transferrins and hemoglobin types among Indians of the Gila River Valley in Arizona. Specimens were procured from the following putative full‐bloods: 909 Pima, 37 Papago, and 124 Maricopa; and from the following known mixed‐bloods: Pima‐Papago 134, Pima‐Maricopa 26, Pima‐Other Indian 41, Pima‐Caucasian 33. These 1304 samples were tested for factors in the A‐B‐O, M‐N‐S‐s, P, Rh‐Hr, Lutheran, Kell‐Cellano, Lewis, Duffy, Kidd and Diego blood group systems, and for additional blood factors (Wr a ), Do a , Vel, Yt a , Co a , Gy a , Sav, and L. W. Serum samples were tested for haptoglobins and transferrins. Hemolysates, prepared from whole blood, were tested for hemoglobin types. The results are presented on appropriate tables as number and per cent of phenotypes for the various blood group antigens and their calculated allele frequencies. Locations of the populations from which blood samples were procured are shown on a map (fig. 1). Tests made by earlier workers on the blood of Arizona Indians and related tribes are presented for comparison and discussed. The usual high frequencies for allele O reported in Amerinds was found among the putatively full‐blood Gila Indians; the 124 Maricopa presented the maximum frequency of 1.000. High frequencies were reported generally for M , s , P 1 , R 1 ( CDe ), R 2 ( cDE ), k (100%) Fy , and Do a alleles. Low frequencies were reported for N, S, r (cde), R° (cDe) , fy , Le 1 w and Di a (Pima only). There was a wide variation in frequencies for jk , and Hp 1 , and there were 17 Transferrin Tf B 1 C observed in 270 Pima samples tested. All the remaining were classified as Tf C except two Tf B;C from mixed‐bloods. All samples tested for Vel, Yt a , Co a , Sav, and Hemoglobin (A) showed the maximum frequency (1.000) for their genes. The following antigens were completely absent: Lu a , Mi a , Vw, Mt a , p, P k , r y (CdE), K, and Wr a . The results of this study suggests that the Papago tribe presents fewer genes of non‐Indian origin than the Pima, and the Maricopa least of the three populations.
