For each trait, the most significant SNP for the QTL that was detected close to the GC gene is shown with its position in base pairs (bp), negative logarithm of the p value [−log(p)], minor allele frequency (Freq), allele substitution effect for the first allele of the SNP (Effect), standard error of the SNP effect (SE), and alleles
