Treatments are 2-sexes and all-kin group (FFMM), 2-sexes and mixed-kin group (FF||MM), and the 1-sex groups (FF||FF and MM||MM). See text for details on the statistics. The body mass of a male paired with 2 females was larger than the body mass of a single male by an average of 3.64 g (±0.83 SE) (paired t test, t = 4.41, P = 0.004, n = 7).
