Fig. 3. Frequencies of maximum responses (across different N_Sel) being higher due to varying the fitness of selected individuals. The dotted lines indicate that the maximum response is numerically higher, whereas the solid lines indicate the maximum response is significantly higher at P = 0.05. Comparisons for short-term selection (cycles 1–5) are across four genetic models (10 QTL, N = 100; 40 QTL, N = 100; 100 QTL, N = 100; and 40 QTL, N = 400) and three levels of heritability (H = 0.20, 0.50, and 0.80). Comparisons for medium-term (cycles 6–15) and long-term (cycles 16–30) selection are across three genetic models (10 QTL, N = 100 excluded) and the three levels of H.
