Figure 3.

Divergence in short and long introns in each recombination region. Divergence between D. melanogaster and D. yakuba for short introns (≤80 base pairs [bp]) and long introns (>80 bp) for regions of high, intermediate, and low frequency of crossing over, and regions of no crossing over. Values reported are means per site, corrected for multiple hits [50]. Error bars indicate 95% confidence interval (CI) obtained by bootstrapping by intron.
