Browser views of haplotype block structure. (A) Blocks deduced from 74 CHM haplotypes are shown in green boxes, along with other information, e.g., SNPs used for the typing, SNP density distributions, and transcripts. The regions examined by pseudoindividual analysis for phasing accuracy assessment are indicated by blue boxes at the bottom. (B) Blocks deduced from CHM haplotypes (green bars) and those from inferred haplotypes of 100 sets of pseudoindividuals (blue bars) are compared.
