Detailed Description
Statement
Reference

Flies have terminal incisions in the wing, and have 3-4 ectopic bristles on veins L2 and L3.

Homozygotes have slightly open wings that are turned down and distally notched. Wings show few trichomes in the triple, double and posterior rows, and etopic bristles on L3 and L4 veins. Transheterozygotes with many other vg alleles lead to the conclusion that this allele is a hypomorph. Like most vg alleles it complements vg83b27.

Wings are approximately one-fourth to one-half the normal width, varying to nearly full length. Wings are incised.

vgs2/+ ; hunspecified/hunspecified flies show no notching of the wing but have more diffused ectopic bristles and ectopic veins. vgs2/vgs2; hunspecified/hunspecified double homozygotes have ectopic bristles almost covering the wing surface, ectopic veins are found all over the wing surface, and an additional row of stout bristles is seen parallel to those found in the proximal part of the wing. N55e11/+ ; vgs2/vgs2 flies show increased cell death in the wing, and many ectopic bristles are found on the wing surface, especially on vein L4. Nnd-1/Y ; vgs2/vgs2 flies show notching of the wing. Nnd-3/Y ; vgs2/+ flies lack the distal portion of the ventral wing blade. The wing is greatly reduced in Nnd-3/Y ; vgs2/vgs2 flies, and marginal structures and veins are missing. These double homozygotes have low viability.
