Balancer recombination happens frequently at 23-25C, strain must be maintained at 16-20C. Homozygous lethal mutation balanced by Dpy- and myo-2p::Venus-marked inversion. Heterozygotes are non-Dpy with relatively dim pharyngeal GFP (Venus) expression, and segregate heterozygous non-Dpy Venus+, non-Venus cc2557 homozygotes (L1 arrest), and Dpy with brighter Venus+ (tmC20 homozygotes).
