Data for the Haploid and SNP Shared Regions and the SNP Ambiguous Regions.

Physical locations were determined using the UCSC Genome Browser (www.genome.ucsc.edu) and the NCBI SNP database (http://www.ncbi.nlm.nih.gov/sites/entrez?db=snp) was used to convert the SNP ID into the RS nomenclature recognized by the UCSC Browser (March 2006). The STRPs were taken from the Marshfield screening sets 13 and 52.
