a: PTC Density and Recombination in D. pseudoobscura
Linear least squares regression of PTC density and recombination rate in D. pseudoobscura Pikes Peak. Similar results were found for D. miranda and D. pseudoobscura Flagstaff (Supplementary figures S1, S2).
b: % Truncation and Recombination in D. pseudoobscura
Linear least squares regression of average predicted sequence truncation of PTC mutations in a recombination window, and recombination rate in that window. D. pseudoobscura Pikes Peak shown. Similar results were found for D. miranda and D. pseudoobscura Flagstaff (Supplementary figures S3, S4)
