  1. Median absolute deviations from medians are in parentheses
  2. Dispersion Bias: Linear regression coefficient of true breeding values onto predicted breeding values
  3. Bold: Medians in bold differ significantly from zero
  4. Superscripts: Different superscripts denote that medians are significantly different
  5. Superscripts are comparable within combinations of Population and column
  6. ss-prefix: Relationship matrices include genomic information
  7. y\(_{A}\): A phenotype with additive genetic effects
  8. y\(_{AD}\): A phenotype with both additive and dominant genetic effects
  9. Purebred: True breeding value is for production of purebred animals
  10. F1: True breeding value is for production of F1-animals
  11. Rotation: True breeding value is for mating with rotationally crossbred animals
