Admixture and Population Stratification in African Caribbean Populations

Annals of Human Genetics, 2008
SummaryThroughout biomedical research, there is growing interest in the use of ancestry informative markers (AIMs) to deconstruct racial categories into useful variables. Studies on recently admixed populations have shown significant population substructure due to differences in individual ancestry; however, few studies have examined Caribbean ...

Admixture and Heterozygosity in West Alaskan Populations

Journal of Biosocial Science, 1983
SummaryAverage heterozygosities for four communities (Savoonga and Gambell on St Lawrence Island, the King Island community now located in Nome, and Wales) are computed from blood allele frequencies. No significant relationship is found between this measure of heterozygosity and the amount of European admixture calculated from gamma globulin haplotype ...

Topological Signatures for Population Admixture

2015
As populations with multilinear transmission (i.e., mixing of genetic material from two parents, say) evolve over generations, the genetic transmission lines constitute complicated networks. In contrast, unilinear transmission leads to simpler network structures (trees).

Population structure and admixture in transplanted Tlaxcaltecan populations

American Journal of Physical Anthropology, 1980
AbstractThe history of the Indian populations from the Valley of Tlaxcala since the Spanish conquest of Mexico has been one of fission and transplantation. A number of Tlaxcaltecan families were relocated by the Spanish and founded new communities such as Saltillo and Cuanalan outside the Valley of Tlaxcala.

The Admixture Linkage Disequilibrium and Genetic Linkage Inference on the Gradual Admixture Population

Acta Genetica Sinica, 2006
Through the theoretical analysis of the admixture linkage disequilibrium (ALD) in the gradual admixture (GA) model, in which admixture occurs in every generation, the ALD is found to be proportional to the difference in marker allele frequencies, P1 - P2, between two subpopulations.

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.

Genetic diversity and admixture patterns in Indian populations

Gene, 2012
India is a diverse land whose population holds the history of waves of human dispersal. Recent studies suggest two major ancestral contributions to most of the Indian sub-populations. However, present day Indians are thought to contain huge genetic diversity derived consequent to multiple cultural, linguistic and geographical variations.

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 ...

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.

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 ...
