Homozygous pharate adults have normal aristae. Their legs occasionally have a severely reduced tarsal claw (7% of animals have at least one claw affected), although the pulvilli and empodium are unaffected.
The ocellar triangle region is compressed in homozygous and sbb6/sbbEal17 flies, resulting in fusion of ocelli, loss of interocellar bristles and loss and mispositioning of the ocellar bristles.
Legs of homozygotes sometimes fuse and have defective segmentation. The most dramatic fusions are seen between adjacent prothoracic legs.
24% of sbbEal17/sbb6 pharate adults have defective claws.
