aPositive additive effects denote trait-increasing effect of the G8.06 allele; additive effects were estimated as half the difference between phenotype averages for the homozygotes
bPercentage of phenotypic variance explained by the QTL
cLOD (logarithm of the odds) above LOD threshold at the 0.05 level of probability obtained through a 1000-iteration permutation test
dRange of the confidence interval position for the QTL
