Predictions of$\mathbf{S}\mathbf{E}\left({\widehat{\mathbf{r}}}_{\mathbf{p}\mathbf{c}}\right)$for typical breeding schemes as a function of the number of half-sib families ( N ).$\mathrm{S}\mathrm{E}\left({\widehat{r}}_{pc}\right)$ were based on Equation 1 with the following input values: Harvest weight in aquaculture (tilapia): n _d = 2, n _o = 40, h² = 0.3, c² = 0.15, r _pc = 0.8. Egg number in laying hens: n _d = 7, $n_{o_p}=10$, $n_{o_c}=5$, h² = 0.2, c² = 0, r _pc = 0.6. Growth rate in pigs: n _d = 10, n _o = 10, h² = 0.3, c² = 0.10, r _pc = 0.7. Growth rate in broilers: n _d = 12, $n_{o_p}=70$, $n_{o_c}=10$, h² = 0.3, c² = 0.05, r _pc = 0.8. Minimum: Lowest possible $\mathrm{S}\mathrm{E}\left({\widehat{r}}_{pc}\right)$ for r _pc = 0.7 refers to a scheme with many dams per sire and many offspring per dam.
