Detected gene flow in Causonis and its contribution to gene tree conflicts. a A cladogram based on the 23taxa-810nu dataset with nodes colored by reticulation index, showing the effects of gene flow. b A cladogram with nodes colored by population mutation parameter theta, showing the effects of ILS. c A cladogram with nodes colored by BS values, showing the nodal recovery in simulated gene trees. d A cladogram with nodes colored by gene concordance factors, showing the level of gene tree variations. Percentages of gene tree variation ascribed to gene flow, ILS, and gene tree estimation error are indicated beside the arrows. e Introgressions in Causonis estimated with SNaQ based on the 8taxa-810nu dataset. Hybrid edges with BS values are denoted by blue dashed lines. Minor inheritance probabilities and BS values are shown in blue and black numbers along the edges, respectively. The edge lengths are shown in coalescent units, with the length of each terminal branch set as 1
