${\mathit{h}}_{\mathit{A}}^2\mathit{ }$: Posterior density median and SD of genomic heritability. ${\mathit{h}}_{\mathit{D}}^2\mathbf{:}$ Posterior density median and SD of genomic dominance variance (% of phenotypic variance). ${\mathit{h}}_{\mathit{A}}^2\mathit{ }$ and ${\mathit{h}}_{\mathit{D}}^2\mathit{ }$were estimated from 10k individuals from the TRN set using all markers via a Bayesian Ridge Regression algorithm. No., number; TRN, training; TST, testing.
