From: Population-specific recombination sites within the human MHC region

Recombination regions identified by SNPs interval displaying EHH decay. Plots illustrate the number of unique HLA allelic haplotypes independently registered drop in EHH (red) and the recombination rates (blue) across (a) HLA-A, (b) HLA-C-B and (c) HLA-DRB1. Recombination segments identified by sperm recombinants (Cullen et al., 2002) are indicated by the pink colored bars and the HapMap-inferred recombination sites (The International HapMap Consortium, 2005) are indicated by the blue colored bars. (d) List of the recombination sites. ‘†’ indicates intervals that reside within sperm typing segments and ‘*’ indicates intervals that overlapped with the HapMap recombination sites. The recombination site was mapped to the Human Reference Sequence Assembly 36.1 (NCBI 36.1) and assigned to a marker that is in the closest proximity to the site.
