Divergence-Based Introgression Polarization [PDF]

Genome Biology and Evolution, 2020
Introgressive hybridization results in the transfer of genetic material between species, often with fitness implications for the recipient species. The development of statistical methods for detecting the signatures of historical introgression in whole ...

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

Disentangling Immediate Adaptive Introgression from Selection on Standing Introgressed Variation in Humans [PDF]

Molecular Biology and Evolution, 2017
Recent studies have reported evidence suggesting that portions of contemporary human genomes introgressed from archaic hominin populations went to high frequencies due to positive selection.

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.

Large-scale introgression shapes the evolution of the mating-type chromosomes of the filamentous ascomycete Neurospora tetrasperma. [PDF]

PLoS Genetics, 2012
The significance of introgression as an evolutionary force shaping natural populations is well established, especially in animal and plant systems. However, the abundance and size of introgression tracts, and to what degree interspecific gene flow is the

The Genetic Cost of Neanderthal Introgression [PDF]

Genetics, 2015
Abstract Approximately 2–4% of genetic material in human populations outside Africa is derived from Neanderthals who interbred with anatomically modern humans. Recent studies have shown that this Neanderthal DNA is depleted around functional genomic regions; this has been suggested to be a consequence of harmful epistatic interactions

Crop–Weed Introgression Plays Critical Roles in Genetic Differentiation and Diversity of Weedy Rice: A Case Study of Human-Influenced Weed Evolution

Biology, 2023
As an important driving force, introgression plays an essential role in shaping the evolution of plant species. However, knowledge concerning how introgression affects plant evolution in agroecosystems with strong human influences is still limited.

Genomic Patterns of Introgression in Interspecific Populations Created by Crossing Wheat with Its Wild Relative

G3: Genes, Genomes, Genetics, 2020
Introgression from wild relatives is a valuable source of novel allelic diversity for breeding. We investigated the genomic patterns of introgression from Aegilops tauschii, the diploid ancestor of the wheat D genome, into winter wheat (Triticum aestivum)

Assessing biological factors affecting postspeciation introgression

Evolution Letters, 2020
An increasing number of phylogenomic studies have documented a clear “footprint” of postspeciation introgression among closely related species. Nonetheless, systematic genome‐wide studies of factors that determine the likelihood of introgression remain ...

The genomic impact of historical hybridization with massive mitochondrial DNA introgression

Genome Biology, 2018
Background The extent to which selection determines interspecific patterns of genetic exchange enlightens the role of adaptation in evolution and speciation.
