  1. - Detection: Percentage of SNPs that are covered by at least five sequencing reads.
  2. - Concordance: Percentage of detected SNPs that matched the HapMap (HapMap Public Release #27; merged II + III) genotype. Due to the underrepresentation of barcode 4 (BC4) in the pools 770 and 792, the detection and concordance rates were lower (assigned in this Table with *).
  3. - gDNA: genomic DNA; WGA: whole-genome amplification; emPCR: emulsion PCR; BC: barcode.
