Heterozygotes have normal wings.
On the legs and wings of mutant adults mechanosensory bristles have two or more bracts.
Gap1B2/+ heterozygotes show wild type wing veins.
Average number of R7 cells per ommatidium is 2.9.
Mosaics in the follicular epithelium cause localized dorsalization of the embryonic cuticle, concomitant with localized disruptions in the nuclear localization of dl gene product.
Severe Gap1 allele.
Mutation has no effect on rhohs.sev rough eye phenotype.
Homozygous females lay eggs with a weak dorsalized egg shell morphology. The embryos are also partially dorsalized.
Rough eye phenotype. Ommatidia are improperly oriented and occasionally are fused. Ommatidia contain supernumerary cells that are characteristic of R7 cells. Supernumerary cells are derived from a cone cell precursor, or a mystery cell, that adopts a neural fate in the disc. Wings show additional longitudinal veinlet branches of the posterior crossvein and delta-like structures. One or two extra sex combs form in ectopic positions and in both sexes duplications of epidermal structures associated with bristles of the distal leg.

RasGAP1B2 suppresses the wing vein loss seen when PtpmegScer\UAS.cLa is expressed under the control of Scer\GAL4en.PU.
The presence of a Gap1B2 background significantly enhances ectopic wing vein formation found in cswY279C.Scer\UAS (Scer\GAL4tub) mutants.
Gap1B2/+ flies expressing GckIIIScer\UAS.T:Ivir\HA1 under the control of Scer\GAL4Bx-MS1096 have ectopic wing veins.
The addition of heterozygous Gap1B2 moderately enhances the rough eye phenotype seen in freddsRNA.Scer\UAS, Scer\GAL4GMR.PF animals. However only 30% of animals exhibited increased roughness.
Gap1B2 pkunspecified (sple) animals show extra bracts, all with the same polarity.
Enhances the extra-R7 cell eye phenotype of sty226/+ heterozygotes.
