Change in recombination rates (± SE) in D. melanogaster caused by directional selection for desiccation tolerance. Significant increases in recombination rates were observed in selection lines (red) compared to control (blue) in intervals cv-v and v-f of chromosome X; net-dp, cn-kn, and c-px of chromosome 2; and h-th of chromosome 3. Asterisks indicate significant differences between selection and control at 0.01 and 0.001 levels using false discovery rate adjusted P values
