Figure 5. Region of decreased heterozygosity in Europeans on chromosome 15 near SLC24A5. (A) Heterozygosity for four HapMap populations plotted as averages over 10-kb intervals. YRI, Yoruba from Ibadan, Nigeria (black); CHB, Han Chinese from Beijing (green); JPT, Japanese from Tokyo (light blue); CEU, CEPH (Foundation Jean Dausset–Centre d’Etude du Polymorphisme Humain) population of northern and western European ancestry from Utah (red). The data are from HapMap release 18 (phase II). (B) Distribution in genome of extended regions with low heterozygosity in the CEU sample.
