Stability or variation? Patterns of lactase gene and its enhancer region distributions in Brazilian Amerindians
Lactase persistence (LP) is the phenotypic trait in which lactase secretion is maintained during adulthood. LP is due to mutations in the LCT enhancer region, located 14‐kb upstream of the gene. In Europeans, the −13910*T allele is associated with LP. In Africans this allele is rare while other mutations in this same region were related to LP. The LCT is highly polymorphic in human populations, but so far Brazilian Amerindians had not been invest…
Autosome STRs in native South America-Testing models of association with geography and language
Information on one Ecuadorian and three Peruvian Amerindian populations for 11 autosomal short tandem repeat (STR) loci is presented and incorporated in analyses that includes 26 other Native groups spread all over South America. Although in comparison with other studies we used a reduced number of markers, the number of populations included in our analyses is currently unmatched by any genome-wide dataset. The genetic polymorphisms indicate a cl…
Dopamine receptor D4 allele distribution in Amerindians: A reflection of past behavior differences
The DRD4 variable number of tandem repeats (VNTR) allele distribution of 172 Guarani (Kaiowá and Ñandeva subgroups) and Kaingang Brazilian Amerindians is reported. These results are integrated with those previously obtained for this ethnic group. Allele frequencies for the three populations are within the interval observed for 15 other Native American populations and show intermediate values between those observed in Amazonia and Patagonia. Signi…
Linkage disequilibrium patterns and genetic structure of Amerindian and non‐Amerindian Brazilian populations revealed by long‐range X‐STR markers
The extent of X‐chromosome linkage disequilibrium (LD) was studied in a southern Brazilian population, and in a pool of samples from Amerindian populations. For this purpose, 11 microsatellites, located mostly in a Xq region comprising ∼86 Mb was investigated. The lower Amerindian gene diversity associated with significant differences between the populations studied indicated population structure as the main cause for the higher LD values in the …
Y‐STR analysis in Brazilian and South Amerindian populations
A sample of 203 Brazilian males from Rio Grande do Sul (RS), the Brazilian southernmost state, was typed for 11 Y‐STR markers (DYS19, DYS389I/II, DYS390, DYS391, DYS392, DYS393, DYS385, DYS437, DYS438, and DYS439). We also typed 42 individuals from two South Amerindian tribes (Kaingang and Guarani) to use the data as parental Amerindian contribution to our analyses. Gene and haplotypic diversities were estimated, with the South Amerindian samples…
Genetic clues about the origin of Aché hunter‐gatherers of Paraguay
Seventeen genetic studies performed among the until recently hunter‐gatherer Aché were reviewed and the corresponding data integrated to general information about this group, and to statistical tests of hypothesis concerning its origin(s). Two features of the Aché gene pool emerge: (a) the distinctiveness in relation to the general pattern of Amerindian genetic data; and (b) the reduced within population genetic variability. As for the origin of …
Population genetic dynamics in the French Guiana region
Three sets of genetic markers (blood group plus protein polymorphisms, mitochondrial DNA, and Y-chromosome) were compared in four French Guiana and one Brazilian Amerindian populations. Spearman's rank correlation coefficient between five gene diversity statistics and historical or present-day population sizes showed significant values, indicating loss of diversity due to population bottlenecks. The three sets of markers furnished distinct admixt…
The β‐globin gene cluster distribution revisited—Patterns in Native American populations
New frequencies for the β‐globin gene cluster haplotypes are presented for the Aché ( N = 82 individuals), Guarani ( N = 76), and Kaingang ( N = 54), three Native South American populations that live in an area between parallels 20°S and 30°S not covered by previous studies at this locus. The haplotype frequencies obtained for the three populations are within the interval observed for 28 other Native American populations. The Aché show much less …
Historical genetics: Spatiotemporal analysis of the formation of the Brazilian population
A total of 1,037 individuals living in five different sociogeographic regions of Brazil were studied in relation to 12 short tandem repeat polymorphisms. The objective was to assess the degree of European, African, and Amerindian contributions to their gene pools. Although most of the genetic variability was found within regions, significant differences were also observed between regions. The estimated relative proportions of the above‐indicated …
Demography and Genetics at the Tribal Level: The Xavante as a Test Case

Electrophoretic protein polymorphisms in Kaingang and Guarani Indians of Southern Brazil
A total of 337 Kaingang and Guarani Indians from two localities were studied in relation to 18 protein genetic loci. In one of the localities, members of these two groups live side by side but show little genetic similarity, emphasizing the influence of cultural factors in the mating behavior of human groups. Integrating the present results with previous ones, it was verified that the genetic relationships among six Kaingang populations do not fo…
Blood polymorphisms and morphological variability in Brazilian Indians
A total of 1,025 adults belonging to four Brazilian tribes were simulataneously studied for 12–16 anthropometric characteristics and 7–11 blood polymorphic loci. Several comparisons using both univariate and multivariate statistical techniques failed to show the negative correlation between these two sets of variables found by other workers. © 1994 Wiley‐Liss, Inc
Protein electrophoretic variability in Saimiri and the question of its species status
An electrophoretic survey of 15 protein systems (22 loci) was employed to determine the genetic relationships among 9 populations (441 individuals) of South American squirrel monkeys ( Saimiri sciureus sciureus, S. sciureus boliviensis , and S. sciureus ustus ). Genetic markers capable of differentiating the second from the two other taxa were observed mainly in the ADA and GPI systems. Heterogeneity for ADA and CA2 between populations from oppos…
Gm haplotype distribution in Amerindians: Relationship with geography and language
A review is made of the Gm haplotype distribution in 60 groups of Eskimos, North, Central and South American Indians, totaling 22,808 individuals. Differences were observed in the shapes of the distribution of Gm*ag and the other markers. Nearly identical values for F ST and average heterozygosities were obtained in the North+Central/South comparisons. North‐South and Southwest/Northeast clinal differences were observed in the Americas using corr…
Genetic variation within two linguistic Amerindian groups: Relationship to geography and population size
Nine Carib and eight Tupi groups were studied for a minimum of eight common polymorphic systems and compared in terms of genetic distances using the methods of Nei and Edwards. Two levels of genetic information were distinguished, one with a maximum of 20 loci and another with a maximum of 12 loci considered. The dendrograms produced consistent, reproducible results, independent of the method used, when a minimum of ten polymorphic systems were i…
