Heterozygotes are WT and segregate WT, dead eggs and DpyUncs. mcDf1 homozygotes arrest as dead eggs.

Heterozygotes are WT and segregate WT, embryonic lethals (embryos fail to elongate) and Sterile Uncs. mc14 identified as a mutation that leads to abnormal lin-26 expression.

Segregates WT, males, Dpy, Rol, DpyRol, dead eggs (mcDf2). Use XX tra-2 males to move mcDf2 around. mcDf2 is an approx. 500 kb deficiency removing a large chunk between mec-2 and sup-7 (non-inclusive).

mcIs17 [lin-26::GFP +rol-6(su1006)]. Rollers. The GFP signal is average in embryos and rather weak in larvae. GFP is detected in the same cells as the endogenous LIN-26 protein, that is hypodermal cells (including rectal and vulval cells), support cells, and the omatic gonad precursors Z1/Z4. The signal is too weak to be detected in uterine cells. mcIs17 insertion site not mapped.

Heterozygotes are WT and segregate WT, DpyUnc and dead eggs. mcDf3 is a deficiency very closely linked to lir-1 - not separable - which removes approx. 250 kb.

Heterozygotes are WT and segregate WT, DpyUncs, and dead L1 larvae that are translucent and often found away from the bacterial lawn (can be difficult to spot on the lawn).

Heterozygotes are WT and segregate WT, Rol Uncs, and dead L2 larvae that are translucent and often found away from the bacterial lawn (can be difficult to spot on the lawn).

mcEx337 [vha-5(+)::GFP + rol-6(su1006)]. Animals with the array are Rollers and GFP+ in the excretory canal. Animals which have lost the array are dead L1 larvae that are translucent and often found away from the bacterial lawn (can be difficult to spot on the lawn).
