Hitchhiking effects of recurrent beneficial amino acid substitutions in the Drosophila melanogaster genome

Peter Andolfatto

Corrected values of π_S and K_a were plotted in Figure 1B, not residuals, as reported in the text. Similarly, corrected values of K_a were plotted in Figure 2. ′′Corrected values'' should also be substituted for ′′residuals'' throughout the text in references to Figures 1B and 2. The author apologizes for any inconvenience these errors may have caused other investigators in the field.
