LV18 C. elegans unc-45(wc1) dpy-1(e1)/daf-7(e1372) par-2(it46) III. Show Description
Maintain at 25C. At 25C, heterozygotes are WT and segregate WT, Dauers (dauer escapers will be Par and give only dead eggs), and DpyUcs which arrest as dead eggs (range from twitching multicellulars to 3-folds that hatch). [There is a greater percentage of hatchlings when the mother is heterozygous (wc1 dpy-1/+). There may also be the possibility of near complete maternal rescue (near full-sized, sterile Dpys), but this has not been routinely observed in the balanced strain (as opposed to wc1 dpy-1/+).] Maintain by picking WT at 25C and scoring for correct segregation of progeny. [3/97: The dauers are not giving dead eggs-they are giving other dauers. Appears that the Par mutation is no longer present.]
