Heterozygotes are wild-type, and segregate wild-type heterozygotes, fertile wild-type males (tra-1 homozygotes), and Dpy. Can recombine: pick individual WT hermaphrodites and check for correct segregation of progeny to maintain.

Stable male/female strain propagated by crossing tra-3(e1767)IV females x tra-3(e1767)IV males. tra-1(e1575) is semi-dominant and transforms both XX and XO into fertile females. Strain contains 4 genotypes: 1) e1575/+; e1767 XX which are fertile females. 2) e1575/+; e1767 XO which are fertile females. 3) e1767 XX which are infertile pseudomales. 4) e1767 XO which are fertile males.

Grows poorly, best at 20C. Self-fertile intersexual XX hermaphrodite due to partial suppression of weak tra-1 allele by smg-2(NMD). References: Zarkower et al. (1994) PMID: 7520378. Hodgkin (1987) PMID:3428597.

Unc-32 hermaphrodites segregating Unc hermaphrodites and Unc Tra homozygous XX pseudomales with variable male tails, hermaphroditic gonads and adult yolk production.

Intersexual self-fertile XX hermaphrodites with Smg (protruding vulva) phenotype. Grows poorly, does best at 20C. Class B1 allele of tra-1 combined with smg-2(NMD), useful for selection of modifiers. Reference: Zarkower et al. (1994) PMID: 7520378

Male/female strain, propagated by crossing. eDp25 carries tra-1 gain-of-function allele. Anatomically normal XX females, tra-1(e1732) XO males, and intersexual tra-1(e1732) XX and e1732; eDp25 XO. References: Hodgkin (1987) PMID: 3428597. Zarkower et al. (1994) PMID: 7520378.

Self-fertile hermaprodite or female. Protruding vulva. tra-1(e2272) XX homozygotes are sterile with abnormal gonads; e2272 mutation is partly suppressed by NMD (smg-2(e2008)), hence double mutants are fertile. Reference: Zarkower et al. (1994) PMID: 7520378.

When singled, hermaphrodites should throw 2/3 hermaphrodites and 1/2 nm2 XX males. The lethal appears to balance the nm2 allele pretty well, but precise recombination mapping has not been performed. The XX males maintain their phenotypic resemblance to the unbalanced strain and are probably not fertile due to obvious gonadal deficiencies. This strain has been successfully grown at 15C and 20C. Both strains appear to have complete penetrance of the mutant phenotypes.

Animals which carry ctDp2 are WT. Animals which have lost ctDp2 are Dpy Males. Maintain by picking WT.

Pick wild-type to maintain. Wild-type hermaphrodites segregate wild-type and dead masculinized embryos. e3026 is nonsense mutation in essential gene Y47D3B.1. Reference: O'Rourke et al (in preparation).

Heterozygous. Maintain by picking fertile hermaphrodites. Stable XX male/female strain (fertile XX females and low fertility XX males); males sire only female progeny. Reference: Strain 3 in Hodgkin (2002) PMID: 12399387.

Maintain at 15C. Heterozygotes are WT, GFP+ in the pharynx and segregate WT (GFP+ in the pharynx), dead eggs (hT2 homozygotes) and non-GFP tra-1(q183) homozygous females. Raise strain at 15C; at 20C many heterozygotes are also feminized. tra-1(q183) is temperature-sensitive for its XX, but not its XO mutant phenotype. At 25C, both q183/q183 and q183/+ are female. At 15C, q183/q183 is still always female, but q183/+ can be hermaphroditic. Maintain by picking fertile GFP worms and checking for correct segregation, since the hT2 balancer is lost at low frequencies.

Pick Unc hermaphrodite to maintain (these will be tra-1/+; unc-42 him-5 dpy-21 XO animals). Segregates Unc hermaphrodites (tra-1/+ III), Unc males (+/+ III), and DpyUnc hermaphrodites (+/+ III). dpy-21 not expressed in XO. dpy-21(e428) V; XX animals are weak Dpy. dpy-21(e428) V; XO animals are non-Dpy.
