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 ...

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).

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.

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 ...

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 effects of admixture and population subdivision on cytonuclear disequilibria

Theoretical Population Biology, 1991
We examine the generation of cytonuclear disequilibria by admixture and continued gene flow. General formulas analogous to the nuclear case are first derived showing that the allelic and genotypic disequilibria from admixture or population subdivision equal their expected value across the contributing (sub) populations plus the covariance across these ...

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.
