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).

Balanced heterozygotes are GFP+ Unc and segregate GFP+ Unc (heterozygotes), non-GFP non-Unc spo-11(me44) homozygotes, and dead eggs (nT1 homozygotes). spo-11(me44) homozygotes are viable and produce more than 90% dead eggs (a large fraction of the survivors are males — strong Him phenotype); cytologically they lack chiasmata in diakinesis-stage oocytes and lack RAD-51 foci. Maintain by picking Unc.

Heterozygotes are WT and GFP+. Segregate syp-3(me42) homozygotes that are non-GFP and lay mostly dead eggs; these mutants form abnormal synaptonemal complex formation during meiosis. Homozygous hT2[bli-4 let-? qIs48] animals are inviable.

Balanced heterozygotes are GFP+ Unc and segregate GFP+ Unc (heterozygotes), non-GFP non-Unc him-3(me80) homozygotes, and dead eggs (nT1 homozygotes). him-3(me80) homozygotes are viable and non-Unc. They produce more than 85% dead eggs and a large fraction (11%) of the survivors are males (Him phenotype). Cytologically they exhibit a reduced level of HIM-3 loading and fewer stretches of SYP-1 than WT. In diakinesis-stage oocytes, they contain a mixture of bivalents and univalents. Maintain by picking Unc.

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.

Sperm activation in virgin males. Poor sperm transfer.

Balanced heterozygotes are GFP+ Unc and segregate GFP+ Unc (heterozygotes), non-GFP non-Unc syp-1(me17) homozygotes, and dead eggs (nT1 homozygotes). syp-1(me17) homozygotes produce 95% dead embryos and 38% 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. qIs50 is an insertion of ccEx9747 with markers: myo-2::GFP expressed brightly in the pharynx throughout development, pes-10::GFP expressed in embryos, and a gut promoter (F22B7.9) driving GFP in the intestine.

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.

Dpy. Unc. meT7 is an end-to-end-to-end fusion of chromosomes III, X, and V. The right end of III is fused to the left end of X, and the right end of X is fused to the left end of IV. Constructed by crossing eT5 and mnT12. meT7 homozygotes produce 92% viable progeny. meT7 heterozygotes are Him and produce many dead eggs.

Sperm activation in virgin males. Very poor sperm transfer.

qIs51 [myo-2p::GFP + pes-10p::GFP + F22B7.9p::GFP]. Heterozygotes are wild-type GFP+ and segregate non-GFP ok197 homozygotes (viable, sterile), wild-type GFP+ heterozygotes, and arrested nT1[qIs51] aneuploids. rad-50 homozygotes are viable, produce more than 95% dead eggs and a large fraction of the survivors are male (Him phenotype).

Heterozygotes are WT and segregate WT, Unc-36 and dead eggs. Maintain by picking WT. Original isolation: BO strain BC1261 unc-22(s727) hermaphrodite heat shocked for 1 hour at 34C. Crossed to N2 strain BC1270 unc-22(s7) unc-31(e169)/nT1 IV; +/nT1 V. Picked individual WT hermaphrodites. Screened for the absence of gravid Unc-22. Retained strain as BC1379.
