Fig. 3. Population density in the ranges used in this report has minimal
influence on dauer formation. In hsd-1(mg433);
ncr-1(nr2022) worms (colored lines), sterol choice (not worm density)
is the major effector of dauer formation at 25°C. hsd-1(mg433)
(black line) single mutants, grown on standard cholesterol, display almost
100% dauer bypass at all population densities tested.
