  1. Number of significant trait-SNP associations at α < 8.79 × 10−6 under 6 possible models: (1) simple GLM (no genetic structure correction); (2) GLM with seven significant principal components of neutral genetic variation; (3) GLM with Q-matrix (K = 2) from STRUCTURE; (4) MLM with EMMA kinship matrix; (5) MLM with EMMA kinship and Q-matrix; (6) MLM with EMMA kinship and significant principal components of genetic variation. aIndicates the optimal model selected by comparison of log-likelihoods using BIC
