Classes of ovarial phenotypes underlying female infertility in PC1/3- and PC2-RNAi-beetles. In this analysis we distinguish two phenotypes: ‘small’ (ovaries are evidently smaller and thinner) and ‘held-egg’ (eggs accumulate in the oviduct without being laid). A Size comparison between a wild-type ovary and a ‘small’ ovary from a PC2-RNAi background. B Ovary displaying ‘held egg’ phenotype (from PC1/3-RNAi background): multiple eggs stuck in the oviducts lead to a disarranged appearance of the whole ovary. Frequencies of both these phenotypes are given in Table 3
