  1. N number of horses included in dataset
  2. Top SNP the top SNP identified from the GWA analysis for back and croup
  3. AF alt frequency of alternate allele
  4. DMRT3 AF alt allele frequency of the alternate allele A in the DMRT3 gene known as the “Gait Keeper” mutation
  5. aThe 177 Icelandic horses included in the present study
  6. bIcelandic horses used for riding but that had not attended breeding field test
