metatarsus (with DeltablX59)
sex comb | ectopic (with DeltablX59)
Compound tarsus seen in T1-4. In homozygous mutants or in Dlbl5/DlblX59 adults, mutant legs develop presumptive borders of leg joints, but do not display growth segmentation and cell shape changes. Occasionally minor duplication of the sex comb is also seen. In the head segment, loss of the basal cylinder in the antenna is seen.
