Table 2. Results from a multiple regression analysis examining the effects of age-independent telomere length, mean offspring sex ratio through a sire's lifetime, and malformation frequency on average of a male's offspring sired through his lifetime.
| Traits | df | SS | F | P |
| TRF (residual from age) | 1 | 2025 | 6055 | 0.013 |
| Mean offspring ratio | 1 | 2.55 | 7.40 | 0.009 |
| Mean frequency of malformations | 1 | 6.16 | 17.9 | <0.0001 |
Model statistics:F 3, 58 = 8.46, P<0.0001, R 2 = 0.30.
