Heterozygotes are WT and segregate WT and Unc Rollers. sC4(s2172) is not viable as a homozygote. As a heterozygote it reduces recombination between unc-76 and rol-9 to 1.8%. Note: This strain has been sequenced and the sC4 balancer contains a large deletion from V:16,060,619 to V:19,331,432 that removes 1,279 genes and has a complex rearrangement on LGIV. See Maroilley et al. Sci Reports (2021)11:18258 for more details. doi.org/10.1038/s41598-021-97764-9

Heterozygotes are wild-type and segregate wild-type (heterozygotes), Dpys (dpy-21 par-4 homozygotes that lay dead eggs), and dead eggs (ozDf2 homozygotes). Maintain by picking wild-type.

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.

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.

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.]

Hermaphrodites are Dpy and segregate males. Males are non-Dpy and Mab. Both sexes show lineage alterations.

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

Dpy hermaphrodites. Males (XO) non-Dpy. M-MATING++++ >30%WT.

Heterozygotes are WT and segregate WT, Lethals (L2/L3 arrest at 20C, some survive to sterile adults at 15C), and DpyRol. Not balanced well: get recombinants. Must maintain by picking hets at each generation and check for proper segregants in F1.

Heterozygotes are WT and segregate WT, DpyUncs and dead eggs. Homozygous wDf1 embryos arrest uniformly as unenclosed balls of differentiated cells. wDf1 formerly called zen-1(e2482). 2/02: dpy-21 appears to have been lost from this strain.

Heterozygotes are WT and segregate WT, UncDpy and Mel. Received new stock from the Horvitz lab 5/04.

TY3936 was derived in 2002 from TY1932 ncl-1(e1865) unc-36(e251); dpy-21(e428) X N2; cloned WT progeny, let self and picked Dpy animals, cloned and selfed, looked for absence of Unc progeny. TY1932 was frozen into TY collection in 1993; built from other strains derived original CB428 stock obtained & frozen in 1983.
