Index of genetic correlation between the simulated reference and three different target populations (one, five, and ten generations after the base reference population) using (a) singular-value decompositions on the matrices of SNP-genotypes as proposed in section IGC calculated from genomic data (\({\text{r}}={\text{a}}+{\text{b}}+{\text{c}}\)); (b) simulated phenotypes and their breeding values solutions as proposed in section IGC calculated from simulated phenotypes (\({\text{log}}\left(\frac{1+{\text{R}}}{1-{\text{R}}}\right)={\text{rlog}}\left(\frac{1+\uprho }{1-\uprho }\right)\))
