  1. * Regression coefficient significantly different from zero at P < 0.05
  2. aBreeds: A = Dutch Landrace, B = Dutch Large White, X = F1 cross of A and B
  3. bHetbreed is the model with heterozygosity within breed
  4. cStandardised regression coefficients are regression coefficients divided by phenotypic standard deviation
