  1. Mc = male combination (1-10), mt = male treatment (small male, large male or sperm competition, ♀ = female). Statistically significant p-values are indicated with boldface. Degrees of freedoms (df) for offspring body mass, total length and yolk volume are given in parentheses. Male combination comprises 10 small males, 10 large males and a sperm competition group (10 small + 10 large males simultaneously). See methods for details.
