(A, B). Probable DIYABC evolutionary scenarios for Cercis canadensis evolutionary history. Here, current C. canadensis populations are north (N1) and south (N2). Also, N1b and N2b represent the populations of N1 and N2 before bottleneck event. On the right side of each scenario, a time scale indicated the timeline of each event (t = 0 is current time, t1-db = bottleneck occurrence, t1/t2 = split of the populations from originating population). Our data was analyzed using two ABC steps resulting in five competing scenarios from the first step (4A), and seven scenarios with possible bottleneck events from the second step analyses (4B). The scenario 2a (B) from step 2 gained the most support in DIYABC analysis and the timeline for the bottleneck (t1-db) and divergence (t1) events of scenario 2a is given in generations. For each scenario, value of relative posterior probability (P) was reported.
