  1. CCFAT carcass fat depth at C site, CEMD carcass eye muscle depth, PEMD post-weaning eye muscle depth, IMF intermuscular fat percentage, SF5 shear force measured at day 5 after slaughter, PWT post-weaning weight, YCFW yearling clean fleece weight, YFD yearling fiber diameter
  2. aThe genetic variance explained by two GRM fitted in the model were divided to the phenotypic variance and then were added up to calculate the overal heritability. The first and the second value in the parentheses are the heritability estimates related to 50k and top SNPs, respectively
