P{GawB} insertion in the first large intron after the translational start site, close to the 5' splice site.
sdSG29.1 mutants show significant increases in the mushroom body and the Kenyon cell cluster sizes, as compared to controls.
Hemizygous males show minor loss of posterior wing margin, especially near the wing hinge.
Heterozygotes have a variable notched wing phenotype.
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. NXK11/sdSG29.1 double heterozygotes show enhancement of nicking along the tip of the wing (compared to NXK11 single heterozygotes) and the veins show delta-like thickening at the end.
