Summary of results for autosomal relatedness in HapMap Yorubans.

Excess autosomal similarity reported in Phase 2 (Hap2) Yoruban mate pairs [13] was confirmed in an independent Phase 3 (Hap3) sample from the same population. However, Hap2 and Hap3 genotypes yielded discrepant results for Hap2∩3 couples (even if the same SNPs were examined; see Table S3). The difference in relatedness between mates and non-mate pairs appears to be driven by a subset of the sample (see Figure 3). The format follows that of Table 1.
