Figure 1: A GWAS for a simulated trait with two causal SNPs randomly chosen from a real A. thaliana SNP data set. GWAS data were simulated by adding phenotypic effects to real genotypic data from A.

Genome-wide association studies (GWAS) are a standard approach for studying the genetics of natural variation. A major concern in GWAS is the need to account for the complicated dependence structure ...
