<i>lin-3(n4441)</i> causes a dominant class A synMuv phenotype.

aAnimals were scored as Muv if any ventral ectopic protrusions were observed. For each strain, animals were scored on three separate days, and % multivulva shown is the average for those three days. SD, standard deviation. n, total number of animals scored. bThese animals were also heterozygous for dpy-17(e164) and unc-32(e189) and descended from lin-3(n4441) homozygous parents. cThese animals were also heterozygous for dpy-5(e61) and descended from dpy-5(e61); lin-3(n4441); lin-15B(n744) parents. dLva, larval arrest. Animals arrested as larvae, precluding the assaying of vulval development.
