Recombination rate estimates in wild-derived strains. (A) Chr. 3 recombination rate estimates from Comeron et al. (2012), and marker-selected pools are depicted. Repeat content (%) and Chr. 3 schematic is plotted above. For the estimates from Comeron et al. (2012), the rates are plotted as the true rates (gray) and the rates after 1 Mb smoothing (red). For the marker-selected pools (DGRP-315, DGRP-360, and Canton-S), rate estimates are restricted to ±0.381 recombinant fraction (equating to 50 cM after Kosambi’s transformation) from the marker. Area around the line demarcates the standard error estimated across the different pools. (B) Correlation of recombination rates of DGRP-315 (red) and DGRP-360 (blue) with unsmoothed (left) and 1-Mb-smoothed estimates (right) from Comeron et al. (2012). Each point is the recombination rate estimate of a 100-kb window. The red and blue lines are the least square regressions. (C) Distribution of the recombination rate of estimates from Comeron et al. (2012) (gray) and of DGRP-315 (red) and DGRP-360 (blue).
