  1. 1. Trait: W6 = Weight at week 6; W6m = Weight at week 6, missing marker genotypes were treated as 3rd allele; W10 = Weight at week 10; observations of all traits were multiplied by 102.
  2. 2. Model: (1) = polygenic; (2) = genomic; (3) = polygenic and genomic; with 100/10/2.5% of the markers allowed to have an effect.
  3. 3. σ 2 p : estimates of the total phenotypic variances.
  4. 4. σ 2 c : estimates of variances attributed to the cage effect.
  5. 5. σ 2 e : estimates of residual variances.
  6. 6. h 2 u : heritability based on the polygenic effect.
  7. 7. h 2 a : proportion of the variance attributed to the genomic effect.
  8. The 95%-highest posterior density intervals have been presented as subscript.
