Box-and-whisker plots of FST values. FST values were calculated for the following: within MZ, within LF, LF versus MZ, and Mbuna versus non-Mbuna. Upper and lower box bounds represent 75th and 25th percentiles, respectively. The solid lines within boxes represent the median value. Whiskers mark the furthest points from the median that are not classified as outliers. Unfilled circles represent outliers that are more than 1.5 times the interquartile range higher than the upper box bound. FST, genetic differentiation; LF, Labeotropheus fuelleborni; MA, Melanochromis auratus; Mb, megabases; MC, Mchenga conophorus; MZ, Maylandia zebra.
