Extended Data Table 2 Female post-mating responses in experiment 3

From: Within-group male relatedness reduces harm to females in Drosophila

  1. We did not find any evidence of differences in female receptivity or egg-laying rate between females mated to AAA versus ABC males (nAAA = 79, nABC = 81, ncontrol = 65). We found a significant treatment effect on mating duration (F2, 222 = 17.98, P < 0.001) but this was due to both AAA and ABC males mating for longer than control males (Tukey, control–AAA, t = −5.839, P < 0.001; control–ABC, t = -3.975, P < 0.001; ABC–AAA, t = -1.023, P = 0.251). Similarly, we found a significant treatment effect on female re-mating propensity (treatment effect, deviance = 10.448, P = 0.005; interaction term, deviance = 1.208, P = 0.547), but this was again due to females mated with AAA and ABC males having a significantly lower probability of re-mating than females mated to control males (Tukey, control–AAA, t = -0.923, P = 0.038; control–ABC, t = -1.133, P = 0.006; ABC–AAA, t = -0.210, P = 0.813). Finally, we did not find significant treatment differences in egg-laying rate (treatment effect, deviance = 5.540, P = 0.063; interaction term, deviance = 0.476, P = 0.788; Tukey, ABC–AAA, z = 1.532, P = 0.275; control–AAA, z = 2.296, P = 0.056; control–ABC, z = 0.976, P = 0.591).
