  1. \(^{\mathrm{{a}}}\) M0: No alignment between GRM and NRM, MG: Modifying the GRM by adding \(\alpha {\mathbf{J}}\), and MA: Extending the NRM to include a meta-founder with self-relationship \(\gamma\)
  2. \(^{\mathrm{{b}}}\) Frequencies to center marker allele counts – all: using all genotypes in the subset and half: assuming frequencies of value 0.5 throughout
