Comparison of global and local recombination patterns in the epiRILs and the 17 F₂ populations (24). (A) Chromosome-wide gene (light gray line) and transposon (dark line) density distribution. The 3-Mb windows bracketing the intersection points between transposon- and gene-dense regions are indicated in orange. (B) Cumulative cM lengths of the epiRILs (thick purple line) and each of the F₂ populations (thin green lines) using the consensus map. Purple shading shows the ±95% confidence interval (CI).The thick green line denotes the average F₂ cumulative length (in cM). The dotted vertical lines define the pericentromeric regions of each chromosome. (C) The distribution of normalized recombination intensities (cM/Mb of a given marker interval divided by the cM/Mb chromosome average) shows suppression of recombination within pericentromeric regions and elevation at its boundaries. Color coding is as in B.
