Values represent slopes from the regression of response to selection on cumulative selection differential, shown for each target eyespot in the color composition and size experiments. Rates of response were significantly different from zero with P < 0.001 except those marked by † (P < 0.005), ‡ (P < 0.01), and NS (P > 0.05). Nested analysis of covariance (ANCOVA) F-values are given for the interaction effect of cumulative selection differential by line nested within selection direction (df = 7,72); **P < 0.0001, *P < 0.01. Superscripts refer to slopes, for each eyespot within an experiment that were judged not significantly different from each other according to Tukey's pairwise multiple comparisons (α = 0.05).
