Embryos exhibit dorsal closure defects. Amplitude and other transmission characteristics of the neuromuscular junction are not significantly different from wild type.
Malpighian tubules are variable in diameter in homozygous embryos.
Embryos exhibit failure of dorsal closure and a weak cuticle.
Large dorsal yolk plug, no cuticle and segment defects.
embryonic lethal central yolk plug; dorsal closure may be incomplete; head involution partial; germ band contraction incomplete. No cuticle evident in cuticle preparations, but mouth parts and spiracles visible. Embryos exhibit considerable movement. no internal organogenesis; prominent
