The dynamics of introgression across an avian radiation

Evolution Letters, 2021
Hybridization and resulting introgression can play both a destructive and a creative role in the evolution of diversity. Thus, characterizing when and where introgression is most likely to occur can help us understand the causes of diversification ...

Genetic evidence of population admixture with European pigs and Southern Chinese pigs in Chinese indigenous Diqing Tibetan breed [PDF]

BMC Genomics
Background The Chinese native Diqing Tibetan pig has a long history of domestication and is distributed in the southernmost region of China compared to other Tibetan breeds.

The recombination landscape of introgression in yeast.

PLoS Genetics
Meiotic recombination is an evolutionary force that acts by breaking up genomic linkage, increasing the efficacy of selection. Recombination is initiated with a double-strand break which is resolved via a crossover, which involves the reciprocal exchange

Genetic Dissection of Wheat Heterosis Identifies Candidate Genes in Biparental and Diverse Hybrid Populations. [PDF]

Plant Biotechnol J
ABSTRACT Understanding how numerous heterotic quantitative trait loci (hQTL) shape heterosis and shifting from hQTL to candidate genes are central challenges. To address these challenges, we performed a systematic, genome‐wide mapping in a biparental population and a population of diverse hybrids.

Population Genomics Unravels the Characteristic Relationship between Introgression and Geographical Distribution in Upland Cotton

Agronomy, 2023
Introgression is an important driver of new genetic variation that increases species and genetic diversity. However, the relationship between introgression and geographic distribution of upland cotton is still unclear.

Different Roles of Introgression on the Demographic Change in Two Snakebark Maples, Acer caudatifolium and A. morrisonense, with Contrasted Postglacial Expansion Routes

Plants, 2022
Hybridization frequently occurs in plant species. With repeated backcross, the introgression may influence evolutionary trajectories through the entry of foreign genes.

Genetic introgression between different groups reveals the differential process of Asian cultivated rice

Scientific Reports, 2022
The Asian cultivated rice consists of two major subspecies: indica and japonica. There are already many reports about the existence of genetic introgression between the two subspecies.

Adaptation by introgression [PDF]

Journal of Biology, 2009
Both selective and random processes can affect the outcome of natural hybridization. A recent analysis in BMC Evolutionary Biology of natural hybridization between an introduced and a native salamander reveals the mosaic nature of introgression, which is probably caused by a combination of selection and demography.

When One’s Not Enough: Colony Pool-Seq Outperforms Individual-Based Methods for Assessing Introgression in Apis mellifera mellifera

Insects, 2023
The human management of honey bees (Apis mellifera) has resulted in the widespread introduction of subspecies outside of their native ranges. One well known example of this is Apis mellifera mellifera, native to Northern Europe, which has now been ...
