Gene flow signals in macaques
A: Gene flow identified by D statistic (corrected P<0.001) at individual level. Numbers in grids representD values, with higher values indicating higher introgression level. Grids without numbers indicate that no gene flow signal was detected. Redder colors indicate higher D statistics. Maximum D value of each individual pair was used for drawing. B: Gene flow identified by D statistic (corrected P<0.001) at species level. The meanings of color and number in grid are the same as that in (A). MaximumD value of each species pair was used for drawing. C: Species tree of macaques with directional gene flow signals. Only signals confirmed by both D and DFOIL statistics are shown here. Arrows indicate direction of gene flow.
