Hermaphrodites are Dpy and Him. Males are non-Dpy and Mab. Males have abnormal bursa and defective rays. Both sexes show lateral hypodermis lineage defexts. M-MATING+POOR <1%WT.

Long. Mechanosensory Abnormal. [NOTE: originally described as carrying e1084, this strain actually carries the e75 allele. The lesion has been verified by sequence analysis. (11/26/2018)]

Hermaphrodites are Dpy. Males are non-Dpy and have abnormal bursae in adult, with swollen rays. Males will mate, but with very low efficiency. [3/98: King Chow isolated a line from the CGC stock that was throwing 100% Mabs. Sent the strain back to the CGC to replace the old stock.]

QL migration reversed, HSN migration defective. Egl.

No FITC uptake by phasmids and amphids. Dauer formation defective. Osmotic avoidance defective.

Defective osmotic avoidance. FITC-.

Defective in osmotic avoidance. FITC-. Dauer defective.

Defective osmotic avoidance. FITC uptake abnormal.

Hermaphrodites are Dpy and segregates males. Males are non-Dpy and have severe tail abnormalities; frequently lethal to adult males.

Heterozygotes are WT and segregate WT, Dpy, and Long Thin Steriles (adults lay no or few eggs). lin-23 animals have excess cell divisions in larval blast cell lineages.

Heterozygotes are weakly Dpy and segregate more weak Dpys, dpy-13 homozygotes and ncl-2 homozygotes. ncl-2 homozygotes are viable, sterile animals with abnormal nucleoli (abnormal refractile appearance by Nomarski). Imperfectly balanced: May Break Down!!

Variable failures in cytokinesis. Mostly viable and fertile.

Some FITC uptake by amphids but not by phasmids. Hypodermal defect.

WT heterozygote, fem-1(e1965) maternal. Segregates WT heterozygotes, WT fem-1 homozygotes that give only fertile female progeny, and UncMor. (Probably has lost mor-2 [Edgley, 4/92]. When confirmed, should be given a new strain name.)

Phenotypically WT. See also CGC 801. eDf24 = let(e2000).

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.

Obligate XX female, XO male strain. Maintain by mating. e2020 is a dominant mutation transforming XX into fertile females. XO animals are partly feminized by starvation or elevated temperatures, therefore the strain cannot be grown at 25C.

Heterozygotes are Unc (shaker; don't move well) and segregate more Shaker Unc, WT and DpyUnc (short and fairly paralyzed). The WT give only males. e1957 previously called sup-21.

Heterozygotes are WT and segregate WT, DpyUnc and dead eggs. Maintain by picking WT.

Heterozygotes are WT (somewhat Unc and Egl) and segregate WT, DpyUnc and dead eggs. Maintain by picking WT.

Unc. Recessive. Levamisole resistant. M-MATING++ 1-10%WT. Also contains an unc-11 mutation->Aixa Alfonso 10/94. See WBPaper00002195. Use ZZ37 for unc-63 reference strain.

Heterozygotes are WT and segregate WT, DpyUnc and fertile females.

Temperature sensitive Fem. Hermaphrodites at 15C, female at 25C. Maintain at 15C.

Non-Dpy 4A;3X hermaphrodites segregating 4A;3X hermaphrodites, 4A;2X males and dead or very dumpy 4A;4X hermaphrodites. Reference: Strain 19 in Hodgkin (2002) PMID: 12399387

Obligate XX female, XO male strain. Maintain by mating. Viable 15-25C. e2046 is a dominant mutation transforming XX into fertile female; minimal effect on XO.

Severely Uncoordinated; Him; feminized at temperatures above 20C. Grow at 15C. Used for generating patroclinous WT males, by exploiting non-disjunction caused by him-8, and dominant sex-linked unc-1.

WT heterozygotes segregate WT, DpyUnc and unhatched eggs.

Male/female strain. Maintain by mating. XX animals are female. XO animals are WT males.

Heterozygotes are WT and segregate WT, Uncs which are sterile and dead eggs (eDf2 homozygotes). Strain breaks down very rarely.

Hermaphrodite at 15C, sterile and gonad-defective at 25C; feminized by smg (NMD) mutations.

eDf43 pka lin-49(e2173). Heterozygotes are WT and segregate WT, Unc-36, and LinDpys. The lin-40 dpy-11 homozygotes are Dpy, Sterile and abnormal. Maintain by picking WT.
