  1. MYint, Milk yield intercept; FYint, Fat yield intercept; PYint, protein yield intercept; HTMYslope, heat tolerance milk yield slope; HTFYslope, heat tolerance fat yield slope; HTPYslope, heat tolerance protein yield slope.
  2. aMulti-trait meta-analysis of single-trait GWAS was performed for intercept and slope traits following21. Values in square brackets are the number of lead SNPs defined as the top significant SNP within 5 Mb non-overlapping windows across the chromosome. The FDR was calculated following the method described by21, where the p value in the brackets represents the cut-off threshold equivalent to FDR < 0.10 for each trait.
