Addition of fz3unspecified to SerD flies enhances the wing notching phenotype seen in these flies. A second copy of fz3unspecified enhances this phenotype further and results in additional posterior margin notching.
sdSG29.1/+ ; SerD/+ flies show an enhancement of wing scalloping with a total loss of sensory bristles along the posterior margin and the loss of some bristles along the anterior margin. Hemizygous sdSG29.1 in combination with SerD/+ results in a deeply scalloped posterior margin. Sensory bristles are completely lost from the posterior margin and there are very few bristles along the anterior margin.
hrgP1/hrgP1; SerD/+ flies show synergistic enhancement of the notched wing phenotype, with deeper wing notching than is seen in either hrgP1/hrgP1 or SerD/+ single mutant flies, and loss of most of the first wing vein. The notching is also not restricted to sites between the second and fifth wing vein. The 'delta' phenotype and wing confluence phenotype of Df(3R)Dl-FX3 flies is suppressed by SerD.
