R166.3. Homozygous marginally-viable 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 gk541 homozygotes (mostly sterile; some animals bear a few progeny, but a population may be difficult to maintain). Pick WT dim GFP and check for correct segregation of progeny to maintain. External left primer: GAGGAGTACACGCCGGATAA. External right primer: AGACCATTTTGCAGGATTGC. Internal left primer: AAGTGCTGACCGAAGAGCAT. Internal right primer: TGGGATTTGAAACGAGAACC. Internal WT amplicon: 1529 bp. Deletion size: 388 bp.
