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 ...

A three-sample test for introgression [PDF]
Molecular Biology and Evolution, 2019 Abstract Many methods exist for detecting introgression between non-sister species, but the most commonly used require either a single sequence from four or more taxa or multiple sequences from each of three taxa. Here we present a test for introgression that uses only a single sequence from three taxa.

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.

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

Systematic Biology, 2022 In the past two decades, genomic data have been widely used to detect historical gene flow between species in a variety of plants and animals. The Tamias quadrivittatus group of North America chipmunks, which originated through a series of rapid ...

Heliyon, 2021 Interspecies hybridization is driven by a complex interplay of factors where introgression plays an important role. In the present study, the transfer of genetic material, between two quite distant fish species from different genera, through spontaneous ...

Characterization of introgression from the teosinte Zea mays ssp. mexicana to Mexican highland maize [PDF]
PeerJ, 2019 Background The spread of maize cultivation to the highlands of central Mexico was accompanied by substantial introgression from the endemic wild teosinte Zea mays ssp.

Genomic architecture and introgression shape a butterfly radiation
Science, 2018 Following gene flow in butterfly genomes The role of hybridization in evolution and species radiations has long been debated. In Heliconius butterflies, introgression was a major factor in their radiation, and the genetic variation it imparted into ...

Cisgenesis, a new tool for traditional plant breeding, should be exempted from the regulation on genetically modified organisms in a step by step approach [PDF]
, 2008 Modern potato breeding requires over 100,000 seedlings per new variety. Main reasons are (1) the increasing number of traits that have to be combined in this tetraploid vegetatively propagated crop, and (2) an increasing number of traits (e.g ...
