K12D12.1. Homozygous lethal deletion chromosome balanced by GFP- and dpy-10-marked inversion. Heterozygotes are WT with relatively dim pharyngeal GFP signal, and segregate WT dim GFP, Dpy bright GFP (mIn1 homozygotes), and non-GFP ok1930 homozygotes (sterile Unc with withered tail, often grotty). Pick WT dim GFP and check for correct segregation of progeny to maintain. External left primer: TCCAATCAAAGGATTCGAGG. External right primer: ATGTCCTGGCCTTCCTTTTT. Internal left primer: GAACCCCTCAAGATCGCATA. Internal right primer: GGCTCCTTTGGCTCTTTCTT. Internal WT amplicon: 3358 bp. Deletion size: 1788 bp. Deletion left flank: TAGTGACGCTGGAGAAAGTTTTTATCCAGT. Deletion right flank: AGCTCCATGGTACAAGAACTTCCGCGGAAA. Attribution: This strain was provided by the C. elegans Reverse Genetics Core Facility at the University of British Columbia, which is part of the international C. elegans Gene Knockout Consortium, which should be acknowledged in any publications resulting from its use.

Heterozygotes are WT and segregate WT, DpyUnc and Unc-4s which give only dead eggs. Maintain by picking WT. Not a strict maternal effect-rescued by male mating.
