Figure 8: Scatterplot of absolute divergence, Dxy, plotted against its standard deviation.

Points are means for every 50 kb window in the genome, with colours denoting windows from genomic islands of divergence (red), those from the three largest islands of divergence (those over 1 Mb in size), two on the X chromosome and one on 2L (yellow) and the windows from the rest of the genome (blue).
