Table 3 Analysis of variance for sum of ovarioles from both ovaries (two generations removed from selection as described in Ovariole number section of the Methods or Results). Comparison of selected vs. control lines via a 3-way, mixed model ANOVA. Linetype (selected vs. control lines), treatment (starved or not starved), block (28 hours or 32 hours starvation) are fixed main effects. Their interactions are also fixed. Line refers to the five replicate lines in each linetype; line is nested within linetype and is random, as are the interactions of line with block and treatment. * =P ≤ 0.05; ** =P < 0.01; *** =P < 0.001
