Weak Egl. Rollers. This strain cannot be distributed to commercial organizations. This strain cannot be used for any commercial purpose or for work on human subjects.

Heterozygotes are WT and segregate WT, Roller Uncs, and a few Dpy mT1 homozygotes. mT1 is an apparent II;III translocation: small broods, lots of dead eggs, and exhibits pseudolinkage between rol-1 II and unc-71 III. The Roller phenotype of rol-1 expresses late and cannot be scored before adulthood. Pick non-Unc hermaphrodites and check for correct segregation of progeny.

Heterozygotes are WT and segregate WT, DpyUnc [mIn1(mc6) homozygotes], and two-fold arrest Let Rol progeny. Well balanced. Male stock. Cross WT males to WT hermaphrodites and check for correct segregation of progeny.

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.

Heterozygotes are slow growing with WT phenotype. Hets segregate more slow growing WT, embryonic lethals (ozDf1/ozDf1) and DpyUncs which are sick and have a maternal effect lethal (none of the offspring from the DpyUncs survive to reproduce). Maintain by picking WT.
