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 ...

Genetic continuity across a deeply divergent linguistic contact zone in North Maluku, Indonesia

BMC Genetics, 2011
Background The islands of North Maluku, Indonesia occupy a central position in the major prehistoric dispersal streams that shaped the peoples of Island Southeast Asia and the Pacific. Within this region a linguistic contact zone exists where speakers of

Geographic patterns of genome admixture in Latin American Mestizos. [PDF]

PLoS Genetics, 2008
The large and diverse population of Latin America is potentially a powerful resource for elucidating the genetic basis of complex traits through admixture mapping.

A Quantitative Summary Statistic for Genetic Admixture

, 2020
The admixture model is a widely popular approach to evaluate the genetic ancestry of humans and other organisms. The model has successfully been used to improve the accuracy of genetic association studies, to further the understanding of human migratory ...

Interactions between genetic admixture, ethnic identity, APOE genotype and dementia prevalence in an admixed Cuban sample; a cross-sectional population survey and nested case-control study

BMC Medical Genetics, 2011
Background The prevalence and incidence of dementia are low in Nigeria, but high among African-Americans. In these populations there is a high frequency of the risk-conferring APOE-e4 allele, but the risk ratio is less than in Europeans.

Parallel Trajectories of Genetic and Linguistic Admixture in a Genetically Admixed Creole Population [PDF]

Current Biology, 2017
Joint analyses of genes and languages, both of which are transmitted in populations by descent with modification-genes vertically by Mendel's laws, language via combinations of vertical, oblique, and horizontal processes [1-4]-provide an informative approach for human evolutionary studies [5-10].

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Race, Genetic Admixture, and Cognitive Performance in the Cuban Population

The Journals of Gerontology: Series A, 2021
Abstract Background Population aging will lead to a dramatic increase in dementia prevalence, which will disproportionally affect racial minorities. The presence of racial differences in dementia prevalence has been widely reported in United States, but there are no relevant studies on this topic in ...
