The Genetic Structure and History of Africans and African Americans. [PDF]

, 2009
Africa is the source of all modern humans, but characterization of genetic variation and of relationships among populations across the continent has been enigmatic. We studied 121 African populations, four African American populations, and 60 non-African

The Kalash Genetic Isolate? The Evidence for Recent Admixture [PDF]

The American Journal of Human Genetics, 2016
To the editor: The recent paper “The Kalash Genetic Isolate: Ancient Divergence, Drift, and Selection,” by Ayub et al.1 suggests that the Kalash people of present-day Pakistan experienced “no detectable gene flow from their geographic neighbors in Pakistan or from other extant Eurasian populations” since their split from those populations over 8,000 ...

eSMC: a statistical model to infer admixture events from individual genomics data

BMC Genomics, 2022
Background Inferring historical population admixture events yield essential insights in understanding a species demographic history. Methods are available to infer admixture events in demographic history with extant genetic data from multiple sources ...

Enhanced methods for local ancestry assignment in sequenced admixed individuals. [PDF]

, 2014
Inferring the ancestry at each locus in the genome of recently admixed individuals (e.g., Latino Americans) plays a major role in medical and population genetic inferences, ranging from finding disease-risk loci, to inferring recombination rates, to ...

Heterogeneity in Genetic Admixture across Different Regions of Argentina [PDF]

PLoS ONE, 2012
The population of Argentina is the result of the intermixing between several groups, including Indigenous American, European and African populations. Despite the commonly held idea that the population of Argentina is of mostly European origin, multiple studies have shown that this process of admixture had an impact in the entire Argentine population ...

Dissecting the within-Africa ancestry of populations of African descent in the Americas. [PDF]

PLoS ONE, 2011
The ancestry of African-descended Americans is known to be drawn from three distinct populations: African, European, and Native American. While many studies consider this continental admixture, few account for the genetically distinct sources of ancestry

Fine-grained habitat-associated genetic connectivity in an admixed population of mussels in the small isolated Kerguelen Islands

Peer Community Journal, 2021
Reticulated evolution -i.e. secondary introgression / admixture between sister taxa-is increasingly recognized as playing a key role in structuring infra-specific genetic variation and revealing cryptic genetic connectivity patterns. When admixture zones

Replicated anthropogenic hybridisations reveal parallel patterns of admixture in marine mussels

Evolutionary Applications, 2020
Human‐mediated transport creates secondary contacts between genetically differentiated lineages, bringing new opportunities for gene exchange. When similar introductions occur in different places, they provide informally replicated experiments for ...
