  1. Abbreviation: REML, residual maximum likelihood.
  2. REML estimates and true simulated values for the entire pedigree are also shown. The true value for the additive variance was calculated as the variance of true genomic breeding values omitting relationships between individuals, and the residual variance was calculated accordingly to obtain a heritability of approximately 0.30.
