The labial lobe is absent in mutant embryos.
Degeneration of the midgut epithelium is seen in homozygous embryos.
The phenotype of fu41 h25 double mutants can be interpreted as an addition of the corresponding single mutant phenotypes, except that the naked cuticle of segments A5 and A7 which is absent in the h25 single mutant, is replaced by a mirror duplication of the remaining denticle belts in the fu h double mutant.
"Pair-rule segmentation phenotype": half the normal number of denticle bands form, due to a deletion of pattern elements from approximately the middle of one segment to a homologous position in the next segment.
The denticle belts associated with the A3/4 and A5/6 composite segments are often fused in homozygous larvae and they may show a more extreme phenotype, resulting in a continuous lawn of denticles throughout the abdomen. Fails to complement the bristle phenotype of h1.
