The use of genomic coancestry matrices in the optimisation of contributions to maintain genetic diversity at specific regions of the genome

Table 4 Average rate of genomic coancestry in genomic regions targeted for minimising coancestry and in the rest of the genome across generations (t) when applying different management strategies (CHR, CHR_{_ove}, REG, REG_{_ove}) for a population of size 100

Rate of genomic coancestry at regions targeted for minimisation (%)

Two different constraints (C) were imposed on the coancestry rate at the rest of the genome when applying strategies CHR_{_ove} and REG_{_ove}
CHR contributions are optimised to minimise f _{m_chr}, CHR _{_ove} contributions are optimised to minimise f _{m_chr} while restricting f _{m_ove-chr}, REG contributions are optimised to minimise f _{m_reg}, REG _{_ove} contributions are optimised to minimise f _{m_reg} while restricting f _{m_ove-reg}
