Figure 8. Circular haplotype dendrograms for polymorphisms across the HBA region of chromosome 16 for 6072 chromosomes from coastal Kenyan individuals.
A: Haplotype dendrogram for the full haplotypes of 179 polymorphisms (chr16:84870-398421). B: Haplotype dendrogram for the core 33kb region surrounding the -α 3.7 deletion (16:207909-241210). Centre shows the dendrogram; middle ring shows individual haplotypes (blue = wt, red = α-thalassaemia); outer ring shows the four major ethnic groupings [Yellow = Chonyi, Green = Giriama, Light Blue = Kauma and Magenta = 'other' groups.
