Heterozygotes are WT and segregate WT, DpyUnc and Unc-4s which give only dead eggs (it12 is temperature sensitive). Maintain by picking WT. Strict maternal effect.

Dominant ts maternal-effect embryonic lethal. Embryos arrest prior to morphogenesis or at two-fold. Non-ts recessive mid-larval lethal. Maintain at 15C. Freezes poorly.

ytEx100 [mel-47(3245 bp rescuing fragment) + rol-6(su1006)]. Maintain by picking Rollers. Animals which have lost the transgene look wt but are fully penetrant Mel. Mutant embryos arrest with less than 100 cells.

ytEx209 contains [pRM8 (mel-46+) + pTG96(sur-5::GFP)]. GFP minus worms are Mel or sterile at 25 C (completely penetrant). Strong but not fully penetrant Mel at 15 C. Culture at 20°C or higher in order not to lose the transgene. To start a yt5 homozygous culture transfer several GFP minus worms to 15°C.

ytEx211 contains [pRM8(mel-46+) + pTG96(sur-5::GFP)]. Larval lethal. GFP minus worms die or arrest as L4 larvae.
