Homozygous sterile allele balanced by bli-4- and GFP-marked translocation. Heterozygotes are WT with pharyngeal GFP signal, and segregate WT GFP, arrested hT2 aneuploids, and non-GFP sterile homozygotes (tm1310 is maternally rescued; progeny of non-GFP animals fail to give viable progeny). Homozygous hT2[bli-4 let-? qIs48] inviable. Pick WT GFP and check for correct segregation of progeny to maintain.

Maintain by picking Unc GFP progeny that produce viable embryos and checking that the non-GFP progeny that are produced fail to give viable progeny. tm1310 is a homozygous sterile allele balanced by bli-4- and GFP-marked translocation. Heterozygotes are Unc with pharyngeal GFP signal, and segregate Unc GFP, arrested hT2 aneuploids, and non-GFP sterile homozygotes (tm1310 is maternally rescued; progeny of non-GFP animals fail to give viable progeny). Homozygous hT2 [bli-4 let-? qIs48] inviable. ok79 heterozygotes are Unc and segregate Uncs, dead eggs, and Him ok79 homozygotes (maternally rescued).
