^aDirection of phenotypic effect; H and M indicate HKR47 and MAS26 alleles, respectively. Additive effect is the effect of substituting a MAS26 allele for an HKR47 allele; its positive value indicates that MAS26 has the positive allele; LR: Likelihood ratio, LOD: log₁₀ of an odds ratio, R²: percent phenotypic variance.
