Heterozygotes are WT and segregate wild-type, wild-type heterozygotes, and Sterile Dpy (spe-4 dpy-20 homozygotes). Homozygous mutants are weak Dpy and partially fertile at 15C. Sterile at 20-25C. Spermatogenesis arrests at the spermatocyte stage.

Temperature sensitive. Weak Dpy and partial fertility at 15C (very few progeny). Sterile at 20C and 25C. Spermatogenesis arrests at the spermatocyte stage.

This strain is difficult and time consuming to maintain. Gives relatively few heterozygotes. Homozygous lethal mutation balanced by Dpy- and myo-2p::Venus-marked inversion. Heterozygotes are paralyzed Unc and Egl with relatively dim pharyngeal GFP (Venus) expression. Heterozygotes segregate heterozygous non-Dpy GFP+ paralyzed Unc and Egl, non-GFP embryonic lethal (homozygous n499), and Dpy with brighter GFP+ (tmC20 homozygous). Remove Dpy from plate to prevent them from taking over. Heterozygotes tend to stack up in parallel clumps. Populations can be enriched by transferring these clumps to new plates and allowing Dpy (tmC20 homozygotes) to crawl out into bacterial lawn, and then picking away Dpy or transferring the clump of Hets to another plate. Derived by balancing n499 from parental strain MT1102 over tmC20 from FX30179.
