Coancestry superposed on admixed populations yields measures of relatedness at individual-level resolution.

PLoS Computational Biology
The admixture model is widely applied to estimate and interpret population structure among individuals. Here we consider a "standard admixture" model that assumes the admixed populations are unrelated and also a generalized model, where the admixed ...

Genome-wide assessment of genetic diversity and population structure insights into admixture and introgression in Chinese indigenous cattle

BMC Genetics, 2018
Background China exhibits a great diversity of ecosystems and abundant cattle resources, with nearly 30 million cattle from 53 indigenous breeds reared in specific geographic regions.

Genomic insights into the admixture history of Mongolic and Tungusic-speaking populations in southwestern East Asia

, 2021
As a major part of modern Trans-Eurasian or Altaic language family, most of the Mongolic and Tungusic languages were mainly spoken in northern China, Mongolia and southern Siberia, but some were also found in southern China. Previous genetic surveys only

Population Genetic Effects of Recent Admixture [PDF]

, 2014
Admixture has played an important role in shaping genetic diversity in many human populations. Quantifying these effects is important not only for answering historical questions, but also for detecting selection, mapping disease genes, and estimating ...

Erratum to: ‘Mutiny on the Bounty’: the genetic history of Norfolk Island reveals extreme gender-biased admixture [PDF]

, 2015
Background\ud \ud The Pacific Oceania region was one of the last regions of the world to be settled via human migration. Here we outline a settlement of this region that has given rise to a uniquely admixed population.

Testing Times: Challenges in Disentangling Admixture Histories in Recent and Complex Demographies

, 2023
Abstract Paleogenomics has expanded our knowledge of human evolutionary history. Since the 2020s, the study of ancient DNA has increased its focus on reconstructing the recent past. However, the accuracy of paleogenomic methods in answering questions of historical and archaeological importance amidst the increased ...

The life history consequences of admixture between intentionally and unintentionally introduced populations of Trissolcus japonicus in Europe

Biological Control
Introducing classical biological control agents from laboratory-reared populations into regions where adventive populations already exist could alter life history traits of the resulting admixed populations, having positive or negative consequences for ...

The History of Admixture in African Americans

, 2019
African American admixture has been a focal topic of genetic studies since the mid-20thcentury. Generally, these studies estimate individual- and population-level African and European ancestry proportions.

Population Genomics of Sub-Saharan Drosophila melanogaster: African Diversity and Non-African Admixture [PDF]

, 2012
Drosophila melanogaster has played a pivotal role in the development of modern population genetics. However, many basic questions regarding the demographic and adaptive history of this species remain unresolved.
