| We selected a grid of 3,380 markers (distributed approximately one per megabase, across the autosomes and the X chromosome) that showed strong differentiation between African- and European-ancestry samples sequenced by the 1000 Genomes Project. Markers previously genotyped on the Illumina Omni 2.5M array were favored and markers with A/T or G/C alleles were avoided. | | We selected a grid of 3,380 markers (distributed approximately one per megabase, across the autosomes and the X chromosome) that showed strong differentiation between African- and European-ancestry samples sequenced by the 1000 Genomes Project.
