Admixture and diversity in West African cattle populations

Molecular Ecology, 2004
AbstractWe present a population genetic analysis of microsatellite variation in 16 West African cattle populations. West Africa represents a unique juxtaposition of different climatic and ecological zones in a relatively small geographical area. While more humid coastal regions are inhabited by the tsetse fly, a vector which spreads trypanosomiasis ...

Admixture and relationships of the population of Jacobina, Bahia, Brazil

American Journal of Human Biology, 1996
As part of the Cornell-Bahia project on leishmaniasis, the people of Jacobina in the state of Bahia in northeastern Brazil were studied for five genetic polymorphisms: ABO blood groups, hemoglobin variants, PGM1, 6PGD, and adenylate kinase. A maximum likelihood method of calculation of frequency of genes for these traits indicates that the ancestry of ...

Admixture’s impact on Brazilian population evolution and health

Science
Brazil, the largest Latin American country, is underrepresented in genomic research despite boasting the world’s largest recently admixed population. In this study, we generated 2723 high-coverage whole-genome sequences from the Brazilian population, including urban, rural, and riverine communities representing diverse ethnic backgrounds. We reveal the

Glyoxalase I polymorphism and racial admixture in the Cuban population

Human Genetics, 1982
The polymorphism of glyoxalase I (GLO I) was demonstrated in the three main racial groups (Caucasian, Mulattoes, and Negroes) of the Cuban population. The GLO I gene frequencies were used to estimate the relative contribution of Negro and Caucasian genes to the genetic makeup of these three groups.

Stratification of Admixture Population: A Bayesian Approach

2019 7th Iranian Joint Congress on Fuzzy and Intelligent Systems (CFIS), 2019
A statistical algorithm is introduced to improve the false inference of active loci, in the population in which members are admixture. The algorithm uses an advanced clustering algorithm based on a Bayesian approach. The proposed algorithm simultaneously infers the hidden structure of the population.

Ethnic Admixture Composition of Two Western Amazonian Populations

Human Biology, 2002
A small riverine community, Portuchuelo (8 degrees 37'S, 63 degrees 49'W), and a rural county, Monte Negro (10 degrees 15'S, 63 degrees 18'W), both in the state of Rondĵnia, Brazil, were studied for the purposes of ascertaining health conditions and the causes of the variability of some infectious diseases.

Racial admixture in a Mestizo population from Mexico City

American Journal of Human Biology, 1995
AbstractSeven genetic systems were used to investigate the racial composition of a sample from a low‐income Mexico City Mestizo group, finding estimates of 0.590, 0.348, and 0.062 of Indian, White, and Black ancestry, respectively. The results are similar to another Mexico City group studied previously and to several Mestizo populations from different ...
