“Choice” Number of samples per replicate where mating took place between unrelated or related partners. “No choice” Number of samples where no mating took place within 10 min. “Individual G-test” G-tests per replicate. “Replicated G-test” G-test for independence over all three replicates, where “heterogeneity” refers to the heterogeneity of the replicates (P > 0.05 indicates the frequency distributions of the replicates are not significantly different from each other) and “pooled” refers to the analysis of the overall mate choice frequencies (where P < 0.05 indicates the choice for unrelated and related partner differs from a 50%:50% distribution)
