EHH patterns around rs2508049 on chromosome 6. (A) EHH for the rs2508049 G and A alleles over a 5-cM (or ≈9 Mb, from 25.06 Mb to 33.93 Mb) region around the SNP in all Northern European populations. The EHH pattern for rs2508049-A in the HapMap Yoruban and Asian (Chinese and Japanese) is also shown, although the absence or very low frequency of the G allele precludes similar analysis of it in these populations. (B) EHH for the rs2508049-A and G alleles using the pre-phased CEU HapMap data, over a 4-cM region (or ≈8 Mb, from 25.06 Mb to 33.07 Mb). A 95 percentile boundary curve from an empirical EHH distribution of 15,325 chromosome 6 SNPs (30650 observations), calculated at 0.1-cM intervals over a 2-cM distance from the cores, is also indicated. Population codes are as follows: (ASN) East Asian HapMap; (AUS) Australia; (CEU) European-American HapMap; (DEN) Denmark; (FIN) Finland; (IRL) Ireland; (NET) Netherlands; (SWE) Sweden; (UK) United Kingdom; (YRI) Yoruba HapMap.
