CB2590 tra-1(e1099)/dpy-18(e1096) III. 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.
CB2810 tra-1(e1575)/+ III; unc-42(e270) him-5(e1490) dpy-21(e428) V. Pick Unc hermaphrodite to maintain (these will be tra-1/+; unc-42 him-5 dpy-21 XO animals).

CB2823 tra-1(e1488) III; eDp6 (III;f). Balanced well. Animals with the duplication are WT. Animals which have lost the duplication have a hermaphrodite gonad and intestine (they are self-fertile); the rest of the body is male.
CB2829 tra-1(e1076) III; eDp6 (III;f). Balanced well. Segregates males.
CB3631 tra-1(e1929) III; eDp6 (III;f). WT hermaphrodites which segregate WT hermaphrodites and tra-1 homozygous XX; weakly masculinized class A7, never fertile as males.
CB3769 tra-1(e1575)/+ III; tra-3(e1767) IV. 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.
CB3989 tra-1(q88) III; eDp6 (III;f). Wildtype hermaphrodites segregating wild-type hermaphrodites and tra-1(q88) XX males, which are fertile and make yolk. Complex rearrangement of tra-1. Reference: Zarkower et al. (1994) PMID: 7520378

Unc-32 hermaphrodites segregating Unc hermaphrodites and Unc Tra homozygous XX pseudomales with variable male tails, hermaphroditic gonads and adult yolk production. Class B2 allele (male tail, sterile hermaphrodite gonad) derived by mutation of tra-(gf) allele e1575. Reference: Hodgkin (1987) PMID:3428597.
CB4890 smg-2(e2008) I; tra-1(e1488) III. 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
CB4900 tra-1(rh132) III; eDp6 (III; f). Fertile hermaphrodites segregating more fertile hermaphrodites and sterile Class A10 tra-1(rh132) XX homozygotes, which have hermaphrodite non-gonadal anatomy and male gonads; Smg (NMD)-sensitive. Reference: Zarkower et al. (1994) PMID: 7520378

Fertile females and fertile males; male-biased sex ratio. Strain with sex determined by a feminizing fragment chromosome (LGIIIR); unusual sex ratio. Reference: Strain 15 in Hodgkin (2002) PMID: 12399387.
CB5133 tra-1(e1732) III; eDp25[tra-1(e1575 e1816)] (III; f). Male/female strain, propagated by crossing. eDp25 carries tra-1 gain-of-function allele.

CB5190 tra-2(e2020) II; tra-1(e1099)/+ III; xol-1(y9) X. 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.
CB5200 smg-2(e2008) I; tra-1(e2272) III. 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.
CB7171 tra-1(e1099) subs-4(e3026) III; eDp6 (III;f). 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).
CP38 Cbr-tra-1(nm2)/Cbr-let(nm28) III. 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.
DZ840 tra-1(ez72[biotag::GFP::TEV::3xflag::tra-1]) III. tra-1(ez72[biotag::GFP::TEV::3xflag::tra-1]) III.
DZ841 tra-1(ez72[biotag::GFP::TEV::3xflag::tra-1]) III; zuIs236. tra-1(ez72[biotag::GFP::TEV::3xflag::tra-1]) III. zuIs236 [his-72(1 kb 5'UTR)::BIRA::GFP::his-72(1 kb 3'UTR) + unc-119(+)]. Location of zuIs236 is not known, but is not in LG III.
EM185 tra-1(e1099) III; ram-5(bx30) X; eDp6 (III;f). Animals with the duplication are WT. XX Animals which have lost the duplication are males (low fertility-gonad morphology variable). Rays abnormal. See also WBPaper0000498.
JK5657 tra-1(q183) III/hT2 [bli-4(e937) let-?(q782) qIs48] (I; III). 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.
