The genetic structure of a tribal population, the Yanomama Indians. 1. Introduction.

Genetic structure of a tribal population, the Yanomama Indians. XIII. Dental microdifferentiation.

Data are presented on the frequency of the following eight dental traits in 635 Yanomama and 65 Makiritare Indians: upper central incisor rotation or winging, shoveling of maxillary incisors, maxillary molar hypocone reduction, Carabelli's trait, mandibular molar cusp number, mandibular molar cusp pattern rotation of second lower premolar, and pattern of second lower premolar cusps. Yanomama de...

The genetic structure of a tribal population, the Yanomama Indians. 3. Seven serum protein systems.

The genetic structure of a tribal population, the Yanomama Indians. XV. Patterns inferred by autocorrelation analysis.

Fifteen allele frequencies have previously been determined for 50 villages of the Yanomama, an Amerindian tribe from southern Venezuela and northern Brazil. These frequencies were subjected to spatial autocorrelation analysis to investigate their population structure. There are significant spatial patterns for most allele frequencies. Clinical patterns, investigated by one-dimensional and direc...

The genetic structure of a tribal population, the Yanomama Indians. XII. Biodemographic studies.

The Yyanomama Indians of Southern Venezuela and Northern Brazil are one of the largest, relatively unacculturated tribes of the tropical rain forest. Over a period of eight years data have been collected from a considerable portion of their territory on estimated age, sex ratio, fertility rates (as determined by physical examination and urine tests), and infant death rates. Although it has been...

The influence of cultural factors on the demography and pattern of gene flow from the Makiritare to the Yanomama Indians.

A single village of Yanomama Indians was found to have frequencies of Dia of 0.06 and of Apa of 0.08, in contrast to 40 other villages where Dia was absent and Ap. quite rare. The source of these genes was identified as a village of Makiritare Indians, but the two allele frequencies were approximately the same or even higher in the Yanomama than in the Makiritare village. Demographic, social an...
