Average observed heterozygosity ${\mathit{H}}_{\text{O}}$ (left), variance of true breeding values ${\mathit{\sigma }}_{\text{TBV}}^2$ (middle), and genetic variance ${\mathit{\sigma }}_{\text{A}}^2$ (right) achieved in each generation of each selection scenario. ${\mathit{f}}_{\text{SEG}},$ kinship; ${\mathit{f}}_{\text{SEG}|\text{N}},$ kinship at native alleles; MC, migrant contribution; OCS, optimum contribution selection; OCS-I, traditional OCS method; OCS-II, OCS with constraint on kinship ${\text{f}}_{\text{SEG}},$ kinship ${\text{f}}_{\text{SEG}|\text{N}}$, and MC; OCS-III, OCS with constraint on kinship ${\text{f}}_{\text{SEG}},$ kinship ${\text{f}}_{\text{SEG}|\text{N}}$, and reduced level of MC; REF, reference scenario; TS, truncation selection.
