Numbers in bold are significantly different from wild type (P < 0.05). Males and females were of the same strain and were 4 days old when mated. n = Number of pairs tested. The unfertilized column shows the unfertilized eggs as a percentage of total eggs laid. Statistical analysis showed nonnormal distribution of this parameter. The Kruskal–Wallis test confirmed statistically significant differences between the medians (P < 0.05). The progeny column shows average offspring per mated pair.
