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.

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 ...

INTROGRESSION AMONG BRITISH BIRCH TREES [PDF]
, 2018 Hybridisation may lead to introgression of genes among species. Introgression may be bidirectional or unidirectional, depending on factors such as the demography of the hybridising species, or the nature of reproductive barriers between them.

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.

Modelling introgression using parent trees.
, 2021 Parent trees represent the possible histories of speciation and/or introgression at a locus, with their probabilities determined by the rate of introgression.

Benefit of Introgression Depends on Level of Genetic Trait Variation in Cereal Breeding Programmes
Frontiers in Plant Science, 2022 We investigated the benefit from introgression of external lines into a cereal breeding programme and strategies that accelerated introgression of the favourable alleles while minimising linkage drag using stochastic computer simulation.

Polygenic Patterns of Adaptive Introgression in Modern Humans Are Mainly Shaped by Response to Pathogens [PDF]
, 2020 Anatomically modern humans carry many introgressed variants from other hominins in their genomes. Some of them affect their phenotype and can thus be negatively or positively selected.

Genome Biology, 2019 Background Evidence of introgression, the transfer of genetic material, between crops and their wild relatives through spontaneous hybridization and subsequent backcrossing has been documented; however, the evolutionary patterns and consequences of ...

Effects of asymmetric nuclear introgression, introgressive mitochondrial sweep, and purifying selection on phylogenetic reconstruction and divergence estimates in the Pacific clade of Locustella warblers. [PDF]
PLoS ONE, 2015 When isolated but reproductively compatible populations expand geographically and meet, simulations predict asymmetric introgression of neutral loci from a local to invading taxon. Genetic introgression may affect phylogenetic reconstruction by obscuring

Correlation and the Structure of Introgressive Populations [PDF]
Evolution, 1966 Anderson (1949) has reviewed in detail the currently available techniques for the study of introgression. He has indicated (Anderson 1954, 1956, 1957) that the use of metroglyphs (the "pictures" used in pictorial scatter diagrams) is the most efficient means of analyzing suspected examples of introgression.
