Fig. 1

CO landscape of chromosome 7. See Supplementary Fig. 3 for other chromosomes. Blue = male COs, red = female COs. Colors on the X-axis indicate chromosome regions: purple = functional centromeres (=CENH3-binding regions59), black = centromere repeats, gray = pericentromeric regions, light gray = distal regions. Insets are cumulative genetic distances across entire chromosomes. Gray triangles in insets are supplemental SNPs added, where needed, to create 1 Mbp intervals. Figures were generated using MareyMap
