=== Native American vs European Ancestry ===

A grid of 1,000 markers selected to be informative for Native American vs. European ancestry. These AIMs were selected to be in low linkage disequilibrium of one another (defined as R2 <= 0.1 in Native American populations, to be conservative) and widely separated (by requiring that they should be at least 250 kbases from other European vs Native American ancestry AIMs. SNPs with significant within continent heterogeneity were excluded.

A grid of 1,000 markers selected to be informative for Native American vs. European ancestry. These AIMs were selected to be in low linkage disequilibrium of one another (defined as R2 <= 0.1 in Native American populations, to be conservative) and widely separated (by requiring that they should be at least 250 kbases from other European vs Native American ancestry AIMs). SNPs with significant within continent heterogeneity were excluded.

The ancestral populations include CEU, TSI, and a population of Spaniards for European ancestry, and six populations of Native Americans: Mayan, Nahuan, Zapoteca, Tepehuano, Quechuan and Aymaran.

These markers were previously genotyped in three samples of European ancestry (consisting of CEU and TSI samples and a population of Spaniards) and six samples of Native Americans ( Mayan, Nahuan, Zapoteca, Tepehuano, Quechuan and Aymaran).

 

Among these SNPs, 998 could be designed into Illumina assays.
