Population differentiation (Y-axis) and recombination rates (X-axis) of autosomal genes following removal of genes associated with overrepresented GO terms. (A) DNA sequence differentiation (FST) between African and Non-African D. melanogaster populations. (B) Gene expression differentiation (QST) between African and Non-African D. melanogaster populations. In all graphs bars represent 95% confidence intervals. Compared to solitary genes, the * indicates a significant difference in recombination rate (X-axis) (P-value ≤ 0.05; Mann-Whitney U tests, two-sided; not corrected for multiple comparisons), and the + indicates a significant difference of the evolutionary property studied (Y-axis) (P-value ≤ 0.05; Mann-Whitney U tests, two-sided; not corrected for multiple comparisons). See Additional File 5 for these analyses prior to the exclusion of genes with over-represented GO terms, and the analysis of X linked genes.
