Gene flow detected in the three Gentiana species. Heatmap summarizing the D-statistic (DBBAA) estimates and their P-values. Taxa P2 and P3 are displayed on the x- and y-axes. Each square represents the highest estimate of each combination of P2 and P3 population. The colour of each square signifies the D-statistic estimate. D-statistic tests for which p < 1×10-6 (i.e. were below a Bonferroni-adjusted P-value threshold of 0.001) are marked with a black asterisk. The white squares in the matrix indicate no data
