Embryos on the left and right have arrested at the 2-fold stage of embryogenesis due to developmental defects caused by the sperm-delivered toxin, PEEL-1. The hatched larva in the center of the image has developed normally because this animal has inherited a single copy of the antidote gene, zeel-1. (See Seidel et al., e1001115.)
