From: Reduced efficacy of selection in regions of the Drosophila genome that lack crossing over
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.
