Heterozygotes are fertile Rollers and segregate fertile non-Rollers (heterozygote), Unc Rollers (unc-51 homozygotes), and non-Unc Rollers that give 96-97% dead eggs (a high % of the survivors are males).

Sperm activation in virgin males. Poor sperm transfer.

Heterozygotes are wild-type and segregate wild-type heterozygotes, DpyUncs (mnC1 homozygotes), and him-14 homozygotes that produce >95% dead embryos and 45% males. Among these surviving progeny, cytologically they have 12 univalents in diakinesis-stage oocytes owing to a failure to form crossovers during meiosis.

Sperm activation in virgin males. Very poor sperm transfer.

meIs8 [pie-1p::GFP::cosa-1 + unc-119(+)] II. Transgene contains a combination of cDNA and genomic sequences of cosa-1 including 212 bp of 3'UTR. GFP is expressed in the adult germline as 6 bright foci per nucleus (one per chromosome pair) from late pachytene through diplotene stages. Homozygous sterile mutation balanced by GFP- and dpy-10-marked inversion. Heterozygotes are WT with relatively dim pharyngeal GFP signal, and segregate WT dim GFP, Dpy bright GFP (mIn1 homozygotes), and non-GFP me103 homozygotes (sterile adult). Pick WT dim GFP and check for correct segregation of progeny to maintain. nbs-1(me103) homozygotes have frayed and aggregated chromosomes at diakinesis of meiosis I. References: Girard C, et al.
