Maternal effect slow growth. See also WBPaper00002456.

Develops slowly (at the clk-3(qm38) rate). Segregates 1/4 Dpy. gro-1(e2400) is maternally rescued. clk-3; gro-1 doubles throw no Dpy and their progeny develop very slowly. To maintain strain pick WT worms singly onto plates and score progeny.

Develops slowly (clk-3(qm38) rate). clk-1(qm30) is maternally rescued. Segregates 1/4 Dpy progeny. To study clk-3; clk-1 doubles place WT worms singly onto plates-the clk doubles will throw no Dpys and their progeny develop extremely slowly (about 3 days to hatch and 10 days for postembryonic development)-they will be sterile when they finally become adults.

Maternally rescued slow growth. Post-embryonic development takes approximately 1.5 days longer then WT at 20C ( clk-2(qm37) is a ts embryonic lethal). Maintain at or below 20C.
