Changes in genetic variance during the recurrent selection process. Genomic assisted recurrent selection (GARS) was compared to the phenotypic recurrent selection (PRS) across five population sizes and two types of traits genetic architecture (oligogenic and high heritability vs. polygenic and low heritability). The five population sizes were designated as par₅_pop₅₀, par₂₀_pop₂₀₀, par₁₀₀_pop₁₀₀₀, par₂₀₀_pop₂₀₀₀, which represent selection of 5, 20, 100, or 200 best parents and randomly intermated to create 50, 200, 1000, or 2000 individuals, respectively. par₁₀₀_pop₅₀₀ and par₂₀₀_pop₅₀₀ represent the selection of 100 and 200 best parents and randomly intermated to create 500 individuals, respectively. Changes in total genetic variance (Y-axis) was ploted against selection years (X-axis). GARS2 and GARS3, with two and three cycles of genomic selection per year, respectively, were compared to one cycle PRS per year. Plotted values are means (+/− 95% confidence interval) from 100 simulations.
