Heterozygotes are WT and segregate WT, Hmp inviable embyros (Hmp: humpback-defective body elongation, abnormal bulges on dorsal side) and Daf Sma (ts Daf).

Heterozygotes are WT and GFP+. Segregates Sma, GFP- worms which have partially penetrant gonadogenesis defects. nT1[qIs51] is probably homozygous lethal. qIs51 is an insertion of ccEx9747 with markers: myo-2::GFP expressed in the pharynx throughout development, pes-10::GFP expressed in the embryo, and a gut promoter F22B7.9::GFP expressed in the intestine. Crosses with this strain generate very few glowing hermaphrodite cross progeny and many glowing male cross progeny. Do not distribute this strain; other labs should request it directly from the CGC. This strain cannot be distributed to commercial organizations. This strain cannot be used for any commercial purpose or for work on human subjects.

Heterozygotes are WT and segregate WT, RolUncs and dead eggs. Homozygous wDf1 embryos arrest uniformly as unenclosed balls of differentiated cells. wDf2 formerly called zen-1(w1). sc8 previously called rol-4(sc8).
