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 ...

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.

Detecting adaptive introgression in human evolution using convolutional neural networks
eLife, 2021 Studies in a variety of species have shown evidence for positively selected variants introduced into a population via introgression from another, distantly related population—a process known as adaptive introgression.

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.

Extensive introgression among strongylocentrotid sea urchins revealed by phylogenomics
Ecology and Evolution, 2023 Gametic isolation is thought to play an important role in the evolution of reproductive isolation in broadcast‐spawning marine invertebrates. However, it is unclear whether gametic isolation commonly evolves early in the speciation process or only ...

Genealogy-based methods for inference of historical recombination and gene flow and their application in Saccharomyces cerevisiae [PDF]
, 2012 Genetic exchange between isolated populations, or introgression between species, serves as a key source of novel genetic material on which natural selection can act.

Introgression of ASIP and TYRP1 Alleles Explains Coat Color Variation in Valais Goats. [PDF]
, 2021 The Valais Blackneck goat is a Swiss goat breed with a characteristic coat color phenotype. Before the revision of the breed standard in 1938, 4 different color varieties of Valais goats were known.

PLoS ONE, 2013 BackgroundIt is widely accepted that interspecific hybridization may induce genomic instability in the resultant hybrids. However, few studies have been performed on the genomic analysis of homoploid hybrids and introgression lines.

Selective sorting of ancestral introgression in maize and teosinte along an elevational cline.
PLoS Genetics, 2021 While often deleterious, hybridization can also be a key source of genetic variation and pre-adapted haplotypes, enabling rapid evolution and niche expansion.
