Genealogy reconstruction from short tandem repeat genotypes in an Amazonian population
We have reconstructed partial genealogies in a sample of 44 SW Amazonian Rondonian Surui, in which 45 dinucleotide short tandem repeat polymorphisms had previously been typed. The genotypes of 488 pairs of individuals having an age difference of 13 or greater were compared, and parentage was excluded if a pair failed to share an allele at more than one locus. In order to test the power of this method, we computed the expected distribution of the …
Class I HLA antigens in two long‐separated populations
Class I HLA antigens have been compared in 5,835 Melanesians of Papua New Guinea and 2,028 Amerindians of South America. The sample includes 50 PNGMel ethnolinguistic groups and 22 SAmlnd groups. Both carry 15 serologically defined antigens and an undefined C allele. Except for A2 in Papua New Guinea and Cwl in South America, these antigens are widely distributed in their respective populations. Nine (A2 and A24, B39, B60 and B62, and Cwl, Cw3, C…

Further blood genetic studies on Amazonian diversity—Data from four Indian groups
Information related to 31 protein genetic systems was obtained for 307 individuals affiliated with the Cinta Larga, Karitiana, Surui and Kararaô Indians of northern Brazil. In terms of genetic distances the Cinta Larga showed more similarities with the Karitiana (both are Tupi-speaking tribes), while at a more distant level the Surui clustered with the Kararaô. The latter, a Cayapo subgroup, showed a completely different genetic constitution from…
Blood genetic systems in four Amazonian tribes
Data on 31 genetic systems were obtained for 421 individuals belonging to the Arara, Arawete, Mundurucu, and Jamamadi tribes of northern Brazil. The Jamamadi depart farthest, and the Mundurucu least, from South American Indian averages. These data are analyzed together with those of 24 other Amazonian groups. Genetic distances and corresponding dendrograms indicate a cluster of 14 related tribes living north of the Amazon river. These genetic res…
Genetic variation within the Tupi linguistic group
A total of 505 individuals belonging to four populations of three Brazilian Indian tribes were variously studied in relation to 34 genetic systems, and the results were compared with South American Indian averages and five other Tupi populations. Rare variants (CdE of the Rh system, PGM211-1, Cp A-CAY1, serum cholinesterase2 C5+ and some Gm combinations) were observed with varying prevalences, and the three tribes showed different degrees of depa…
Genetic variation within a linguistic group
A total of 136 individuals were studied in relation to 31 genetic systems, and the results were compared with South American Indian averages and previous surveys on the Wayana of French Guiana and Surinam. The information was afterwards integrated with data from other Carib groups, and two types of genetic distances (Nei's and Edwards') were calculated a) between five groups, considering ten systems; and b) between nine groups, using five systems…
Failure of linguistic relationships to predict genetic distances between the Waiãpi and other tribes of lower Amazonia
Data on blood group, serum protein, erythrocyte enzyme, and histocompatibility antigen (HLA) traits are presented for the Waiãpi, a Tupispeaking tribe of the Brazilian and French Guianas. Intra‐ and intertribal comparisons have been made between these data, and previously published data from French Guiana, from another Tupi tribe and from other tribes of neighboring areas, and from the continent as a whole. For this purpose, we have modified the …

Restriction and persistence of polymorphisms of HLA and other blood genetic traits in the Parakanã Indians of Brazil
Results concerning HLA types and 22 other blood genetic systems are reported for the Parakanã Indians of northern Brazil, a tribe that is notable for the light color and pilosity of some of its members. No clear evidence of Caucasoid admixture was found, but the Parkanã show unusual frequencies in the EsD 1 , PGM 1 1 , Gc 2 , Cp B , Fy a , Di a , and L M genetic markers. In addition, the very rare Rh allele r y is present, as well as what seems t…
Part four
Demographic characteristics of eight diverse unacculturated tribes of Pará state of Brazil are examined. Serial censuses reveal highly unstable patterns and standard demographic procedures based on the assumption of a steady state are not applicable to current data. Postulating that prior to regular contacts with the national culture the population changes in the several tribes were asynchronous, we have used the average of the several tribes as …
Blood groups and H‐Le a salivary secretion of Brazilian Cayapo Indians
Five hundred and twenty‐six individuals from four populations were studied in relation to the ABO, MNSs, P, Rh, Lutheran, Kell, Lewis, Duffy, Kidd, Diego and I systems, as well as for the Wright antigen of blood groups. The H‐Le a salivary secretion of 406 of them was also investigated. Considering the gene markers which show variation in South American Indians, the Cayapo frequencies are in the middle of the distribution range for genes L Ms , R…
