Homozygotes have a vgnw wing phenotype. Postscutellars and halteres are missing. vg83b22/vg83b27 transheterozygotes have crumpled and blistered wings, intermediate halteres and wild-type postscutellars.
homozygous wing phenotype like that of vgnw halteres absent postscutellar bristles absent homozygous viable female-fertile?
