Fig. 2From: A history of hybrids? Genomic patterns of introgression in the True GeeseDistribution of divergence times for Lesser White-fronted Goose with all Anser species and for Cackling Goose with all Branta species. All distributions show a single peak, indicating gene flow during divergence. The divergence time of several gene trees was close to zero, suggesting low levels of recent gene flow between certain speciesBack to article page
