Most homozygotes survive until the pharate adult stage. Approximately 50% of cg1/cg3 animals eclose to adult stages, with most of the remaining animals dying as pharate adults. cg1/cg3 flies have defects in some combination of the posterior compartment longitudinal veins L4 and L5. Defects in vein L4, ranging from a slight thinning of the vein to gaps of increasing size are seen in 100% of wings. Defects in wing vein L5 are seen in less than 25% of flies. Rarely (less than 1%), outgrowths are seen in the costal region of the anterior wing margin. cg3/cg07659 animals survive to the pharate adult stage but never eclose. cg3/cg07659 males have highly disorganised sex combs with as much as a threefold increase in the number of sex comb teeth. The pre-apical bristle may also be duplicated. cg3/cg07659 legs discs show a substantial increase in the relative size of the anterior compartment.
Df(2R)en-11/+, cg3 has visible | dominant phenotype
cg[+]/cg3 is an enhancer of wing vein L4 phenotype of ciW
Df(2R)en-11/+, cg3 has wing vein L4 phenotype
Df(2R)en-11/+ ; cg3/+ double heterozygotes have a gap in wing vein L4. The wing vein L4 defects observed in ciW/+ heterozygotes are enhanced by one copy of cg3.
