Detecting the True Extent of Introgression during Anthropogenic Hybridization
(2019) In Trends in Ecology and Evolution 34(4). p.315-326- Abstract
Hybridization among naturally separate taxa is increasing owing to human impact, and can result in taxon loss. Previous classification of anthropogenic hybridization has largely ignored the case of bimodal hybrid zones, in which hybrids commonly mate with parental species, resulting in many backcrossed individuals with a small proportion of introgressed genome. Genetic markers can be used to detect such hybrids, but until recently too few markers have been used to detect the true extent of introgression. Recent studies of wolves and trout have employed thousands of markers to reveal previously undetectable backcrosses. This improved resolution will lead to increased detection of late-generation backcrosses, shed light on the... (More)
Hybridization among naturally separate taxa is increasing owing to human impact, and can result in taxon loss.

Genetic markers can be used to detect such hybrids, but until recently too few markers have been used to detect the true extent of introgression. Recent studies of wolves and trout have employed thousands of markers to reveal previously undetectable backcrosses. This improved resolution will lead to increased detection of late-generation backcrosses, shed light on the consequences of anthropogenic hybridization, and pose new management issues for conservation scientists.
