Data from 16 competitive IVF assays.

Two replicate assays where run in parallel, one for which ova were donated by females from the Rat Island (high-level postcopulatory sexual selection) population and the other from the Whitlock Island (low-level postcopulatory sexual selection) population. Across the replicate assays, the total number of ova ovulated (ANOVA: F1, 14 = 0.054, P = 0.821; a) and the proportion of ova that were fertilized (GLMM: F1, 14 = 0.837, P = 0.376; b) did not differ between ova from females of the different populations. The success of males from the Rat Island (high-level) population is expressed as proportions of the total number of fertilized ova (c).Data from 16 competitive IVF assays.
