Population genetics and the phylogeographic structure of dabbling duck species were investigated using 5′-end sequencing of the mtDNA control region and ODC-6 of nuclear DNA. Overall, a weak phylogeographic structure and low genetic differentiation in mallards (Anas platyrhynchos) and European wigeons (Anas penelope) were discovered, which was likely due to the presence of large, long-term population sizes and significant intracontinental dispersal. Haplotypes of the mtDNA of spot-billed ducks (Anas zonorhyncha) and American wigeons (Anas americana) were found in Mallard and European wigeon samples, respectively. This presence of closely related species haplotypes in the gene pools of these species is consistent with the occurrence of historical and contemporary hybridization and incomplete sorting of haplotype lineages in mallards and wigeons
