K stands for the matrix of pairwise distance for all SNPs in the genome not included in the GLS loci. The distance matrices for the GSL loci correspond to MAM, AOP, and GS-OH. Interactions are marked by $\mathrm{\ast }$. $r^2=0.0969$ (P$<0.00001$). Significance: ***P $<$ 0.001; **P $<$ 0.01; ns, nonsignificant.
