Haplotype blocks on chromosome 22 from The University of Oxford and The Wellcome Trust Sanger Institute, as described in Dawson, E. et al. A first-generation linkage disequilibrium map of human chromosome 22. Nature 418, 544-8 (2002).
The location of each haplotype block is represented by a blue horizontal line with tall vertical blue bars at the first and last SNPs of the block. Blocks are displayed as starting at the first SNP and ending at the last SNP of the block. Individual SNPs are denoted by smaller black vertical bars. At multi-megabase resolution in dense display mode, clusters of tall blue bars may indicate hotspots for recombination.
NOTE: Haplotype block annotations appear only on chromosome 22.
Thanks to The University of Oxford and the the Sanger Institute for providing these data.
