The cuticle patterns produced by gd mutant embryos after injection of gd RNA

gd RNA,  mg/ml	Number of cuticles	% Partially rescued	% Rescued to wild type	% Ventralized
0.03	91	31	66	3
0.15	40	38	20	42
0.75	52	6	2	92
1.50	64	0	0	100

Embryos from gd⁷/gd⁷ mothers were injected with gd RNA at the indicated concentrations, and cuticles produced by injected embryos were examined. Partial rescue includes cuticles having the dorsolateral Filzkörper (arrow in Fig. 2D) or the Filzkörper and some ventral denticles (inverted v in Fig. 2D). Wild type indicates embryos that hatched out of the eggshell (Fig. 2D) or unhatched embryos having a wild-type cuticle pattern. Ventralized represents cuticles having ventral denticles but no Filzkörper (Fig. 2F), which were produced by embryos having a ventralized phenotype at the gastrulation stage (Fig. 2E).
