A browser view of extended shared haplotypes. The density of extended shared haplotypes (ESHs) >1 Mb among all pairs of haplotypes of 74 HapMap CEU chromosomes, 74 HapMap JPT chromosomes, and 74 CHM chromosomes from this study are shown. The total numbers of SNPs participating in the ESH analyses were 772,839 (CEU_all), 698,909 (JPT_all), 274,957 (CHM_all), 89,164 (CEU_shared), and 93,531 (JPT_shared and CHM_shared). The density was determined as the number of overlapping ESHs at 100-kb intervals. ESHs spanning centromeres may be artifactual because SNPs are sparse or absent in these regions. The bars in the overview track are color-coded to indicate ESH density: white for zero, light to dark blue for one to 860, and black for >860. Red vertical line indicates the position of the ALDH2 locus.
