Fig. 2: Tests of introgression between Ursus arctos (brown bears) and U. americanus (American black bears) using Tremarctos ornatus (Andean bear) as the outgroup and an ancestral Ursus reference genome for mapping.

From: Phylogeography of introgression: Spatial and temporal analyses identify two introgression events between brown and American black bears

Fig. 2

Colors represent the population of each animal used as the p1 (exterior/line) and p2 (interior/fill). Z-scores greater than 3 show significant introgression between the p1 American black bear and brown bear; where scores less than -3 indicate gene flow between the p2 animal and brown bear.
