The genetic admixture in Tibetan‐Yi Corridor

American Journal of Physical Anthropology, 2017
AbstractObjectivesThe Tibetan‐Yi Corridor located on the eastern edge of Tibetan Plateau is suggested to be the key region for the origin and diversification of Tibeto‐Burman speaking populations and the main route of the peopling of the Plateau. However, the genetic history of the populations in the Corridor is far from clear due to limited sampling ...

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 Indicative Interval (AII): a new approach to assess trends in genetic admixture

Genetica, 2014
The genetic admixture is a dynamic and diachronic process, taking place during a great number of generations. Consequently, a sole admixture rate does not represent such an event and several estimates could help to take into account its dynamics. We developed an Admixture Indicative Interval (AII) which gives a mathematical key to avoid this problem by

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.

Demographics of genetic admixture and expansion

BioSystems
We explore the dynamics of genetic admixture and expansion, as well as language assimilation, through mathematical-demographic modeling. Our primary goal is to address the population-genetics 'paradox' wherein autosomes and allosomes present markedly different, if not contradictory, pictures of past migrations. We demonstrate that this paradox may find

Pharmacogenomics in the Americas: The Impact of Genetic Admixture

Current Drug Targets, 2006
In this review we focus on the impact of genetic admixture on pharmacogenomics in the American continent, where five centuries of intermarriage between Amerindians, European and Africans, resulted in the extensive population heterogeneity observed nowadays.

Genetic kinship and admixture in Iron Age Scytho-Siberians

Human Genetics, 2019
Scythians are known from written sources as horse-riding nomadic peoples who dominated the Eurasian steppe throughout the Iron Age. However, their origins and the exact nature of their social organization remain debated. Three hypotheses prevail regarding their origins that can be summarized as a "western origin", an "eastern origin" and a "multi ...

Genetic admixture accelerates invasion via provisioning rapid adaptive evolution

Molecular Ecology, 2019
AbstractGenetic admixture, the intraspecific hybridization among divergent introduced sources, can immediately facilitate colonization via hybrid vigor and profoundly enhance invasion via contributing novel genetic variation to adaption. As hybrid vigor is short‐lived, provisioning adaptation is anticipated to be the dominant and long‐term profit of ...

Management increases genetic diversity of honey bees via admixture

Molecular Ecology, 2012
AbstractThe process of domestication often brings about profound changes in levels of genetic variation in animals and plants. The honey bee, Apis mellifera, has been managed by humans for centuries for both honey and wax production and crop pollination. Human management and selective breeding are believed to have caused reductions in genetic diversity

Power of the admixture test to detect genetic heterogeneity

Genetic Epidemiology, 1991
AbstractSeveral dominant genetic diseases which appear to be homogeneous are the expression of genetic mutations at several loci. The power to detect linkage by likelihood methods is diminished for heterogeneous, as compared to genetically homogeneous, disorders.
