Efficiency of markers and methods for detecting hybrids and introgression in stocked populations

摘要: Detection of hybridization and introgression in wild populations that have been supplemented by hatchery fish is necessary during development conservation management strategies. Initially, allozyme data more recently highly polymorphic microsatellite markers used to obtain this information. We both assess the effectiveness four assignment methods (Structure, NewHybrids, Baps GeneClass) detect stocked populations. Simulations hybrid genotypes from real parental revealed number type with Structure, NewHybrids can identify as admixed most first second generation hybrids well backcrosses. In populations, rates estimated different were correlated. However, slight disagreements observed at population individual levels. Overall, fully Bayesian Baps) performed better than partially (GeneClass) tests. collections, analyses limited because lack a native baseline. all cases, efficiency was reduced increased.
