Table 3 Comparisons of fitness components in within- and between-line crosses (excluding crosses where no eggs where produced).
Trait | Within-line | Between-line | F – tests of equality of means |
|---|---|---|---|
Lifetime egg production | 23.73 (1.53) | 23.05 (0.4) | F1,946 = 0.17, P = 0.67 |
Lifetime offspring production | 16.07 (1.48) | 19.9 (0.4) | F1,950 = 5.93, P = 0.015 |
Egg-to-adult survival (%) | 62.01 (0.03) | 79.75 (0.01) | F1,946 = 30.97, P < 0.001 |
F1 productivity | 16.97 (0.82) | 31.82 (0.25) | F1,2903 = 209, P < 0.001 |
