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

Table 5 Average rate of genomic coancestry (in %) in specific regions and in the rest of the genome across generations (t), when applying two different management strategies (OVE and OVE_{_reg}) for populations of two different sizes (N)

Two different constraints (C) were imposed on the coancestry rate in each of the specific regions when applying strategy OVE_{_reg}
OVE contributions are optimised to minimise f _{m_ove}, OVE _{_reg} contributions are optimised to minimise f _{m_ove} while restricting Δf _{m_reg}
