Results of the study on real data: (a) Index of genetic correlation (\({\text{r}}\)) between the reference and target populations using simulated phenotypes and their breeding values solutions as proposed in section IGC from simulated phenotypes. (b) Relationship between the realized prediction accuracy \({\text{R}}=\widehat{{\text{cor}}}\left({\widetilde{\mathbf{g}}}_{2},{\mathbf{y}}_{2}\right)\) and the squared accuracy of the breeding values of the reference population, \({\hat {\uprho} }^{2}={\widehat{{\text{cor}}}}^{2}\left({\widehat{\mathbf{g}}}_{1},{\mathbf{y}}_{1}\right)\)
