Quantitative analysis of known synthetic lethal interactions (Interaction Gene1 + Gene2; see below for references) after combinatorial RNA interference (RNAi) in wild-type or RNAi-hypersensitive rrf-3 worms [19]. Percentages of average wild-type brood size (BS) and embryonic survival (ES) rates resulting from RNAi targeting each gene individually (Gene1 or Gene2) as well as targeting both genes simultaneously (Gene1 + 2) are shown. A synthetic interaction (Syn) was scored positive for p < 5.0 × 10-02 (by Student's t-test). References for genes tested: mec-8 + sym-1 [21]; sop-3 + sop-1 [22]; tbx-8 + tbx-9 [23]; hlh-1 + unc-120, hlh-1 + hnd-1, unc-120 + hnd-1 [24]; and egl-27 + egr-1 [25].
