For each QTL region and trait analyzed with the 660 K array, the most significant SNP is presented with ID, minor allele frequency (MAF), allele substitution effect, proportion of explained genetic variation (%σ² _a), proportion of explained phenotypic variation (%σ² _p) and significance (p-value corrected for genomic control)
