  • a The fixed effect of the ABCG2_49 alleles.

  • b The fixed effect of the OPN_3907 alleles.

  • c Random effect of a putative QTL.

  • d Random effect of a second putative QTL.

  • e The effect of the gene in the average environment. Int, interaction.

  • f The interaction term between the gene and the herd-year solution, i.e., the effect of the gene on the environmental sensitivity.

  • g The model was run twice, once with ABCG2 as the only single gene and once with OPN as the only single gene.
