This would theoretically result in greater power of discovery in GWAS, as the analysis 91 is most powerful for variants with higher minor allele frequency. Web13 sequenced and included in the reference panel for two admixed populations (African and Latino 14 Americans) and two European population isolates (Sardinians and Finns). We develop a 15 framework to identify powerful and cost-effective GWAS designs in these populations given 16 current sequencing and array genotyping costs.
