Recombination rate estimations for chromosome 1. (A) Recombination rates estimated by LDhat (black lines, unsmoothed) and SNP density (scaled to 100) across the chromosome (red line). (B) Comparison of recombination rates across chromosome 1 between the rates estimated by LDhat (red line) and a pedigree-based genetic map by Cox et al. (2009) (blue line). Both lines are recombination rates smoothed over windows of 10 Mb and shifted every 1 Mb. (C) Correlations between the recombination rates estimated from mouse crosses, Cox and Paigen (green line), between Cox and the current study (blue line), and Paigen and the current study (red line). The correlations (y-axis) are shown as a function of the window size in Mb (x-axis). The correlations were calculated with different sizes of nonoverlapping windows.
