Ancestral haplotype reconstruction in endogamous populations using identity-by-descent
Fig 7
Example of the grouping algorithm on a genotyped individual.
Each horizontal line represents one IBD segment shared with a cohort of other genotyped individuals. IBD segments of the same color represent haplotypes, and have a consistent sequence along the chromosome. Small vertical lines represent heterozygous sites between the two haplotypes. (A) Chrom 8: very occasionally we merge groups incorrectly and obtain three groups. (B) Chrom 21: we almost always see two clear haplotypes (here we also see a large stretch of homozygosity).
