Heterozygotes are Unc and express myo-2::GFP in the pharynx. unc-42(e270) spe-42(eb5) homozygotes are Unc and non-GFP. Whle unc-42(e270) spe-42(eb5) self progeny have not been quantified, spe-42(eb5) alone produces 9 self progeny at 16C and <1 self progeny at 25C. The Spe defect can be rescued by WT sperm. Homozygous nT1[unc-?(n754) let-? qIs50] are embryonic lethal.

asEx83 [spe-19(+) + myo-3p::GFP]. Pick GFP+ to maintain. asEx83 contains 7.3kb genomic fragment including spe-19 (Y113G7A.10) and 850bp of upstream sequence. Transgene rescues spe-19(eb52) sperm activation defect. GFP+ hermaphrodites are fertile. non-GFP hermaphrodites are sterile. All males are fertile.
