Heterozygous adult males have a normal abdominal pigmentation pattern. Abd-Biab7-R73/Df(3R)Abd-BS10 males show abdominal transformations; the A7 tergite is fully developed in these animals, and both A6 and A7 show pigmentation defects that resemble intermediates of the A4 and A5 patterns. The A5 tergite shows the A4 pigmentation pattern, as indicated by a complete loss of pigment in the anterior half of the dorsal cuticle.
Segments A6 and A7 show a more posterior identity when heterozygous with Abd-B- than when hemizygous.
A6 and A7 are transformed to A5.
Phenotype may be due to a defect in some aspects of the maintenance function, rather than the lack of a specific enhancer.
