Balanced heterozygotes are Unc and segregate Unc (heterozygotes), non-Unc syp-2(ok307) homozygotes, and dead eggs (nT1 homozygotes). syp-2(ok307) homozygotes are viable and non-Unc. They produce 96% dead eggs and 44% males; cytologically they lack chiasmata in diakinesis-stage oocytes, exhibit persistent polarized nuclear organization during earlier meiotic prophase, lack synaptonemal complexes, and exhibit unstable pairing of homologous chromosomes.

H16O14.1. Homozygous sterile deletion chromosome balanced by GFP-marked translocation. Heterozygotes are WT with pharyngeal GFP signal, and segregate WT GFP, arrested nT1[qIs51] aneuploids, and non-GFP ok3074 homozygotes (sterile with no eggs, often with vulval blip). Homozygous nT1[qIs51] inviable. Pick WT GFP and check for correct segregation of progeny to maintain. External left primer: GGACGGCCAGATTCAGTAAA. External right primer: CGTAATGGCGGTTTTTGATT.
