  • Cell corpses were scored in 4-fold stage embryos and are shown as means±s.e.m. At least 15 embryos were scored for each genotype. The complete maternal genotypes are (from top to bottom): unc-76, hT2/sm237, sm237 and hT2/ok1246. The complete zygotic genotypes are (from top to bottom): hT2/+;unc-76/+, sm237/+ sm/s13 (Psur5:gfp)/+;unc-76/+, red non-green progeny of hT2/ok1246;qxEx58 (Psur5:rfp) males crossed with unc-76, green progeny of hT2/sm237, non-green progeny of hT2/sm237, green progeny of hT2/+ males crossed with sm237, red non-green progeny of hT2/ok1246;qxEx58 males crossed with sm237, green progeny of sm237/+ sm/s13/+ males crossed with sm237, progeny of sm237, green progeny of hT2/ok1246 and non-green progeny of hT2/ok1246.
