    Description

    FlyBase curator comment: this entry is used to capture phenotypic information when the particular allele (or allele combination) used by the author could not be determined but the context of the experiment suggests that the phenotype being described is some kind of loss of function.

        Mature homozygous adult flies have a significantly lower body glycogen content than mature wild-type flies.

        (Barnes, 1994)

        There is a decrease in the apical cell region of the wing discs in homozygous larvae.

        (Ryerse and Nagel, 1984)

        Flies show notum duplications, due to a homeotic transformation of wing base structures to notum.

        (Mglinetz and Balakireva, 1982)

        vgW/vgunspecified flies completely lack wings and halteres and the scutellum is deformed. The postscutellar bristles are usually absent. Development is slow, and only 20-30% of flies eclose. Viability and fertility is reduced.

        vgunspecified; M(3)801 heterozygotes are normal at 22oC. At 29oC they have nicks in the apical part of the wing. su(f)8/Y ; vgunspecified/+ flies are normal at 22oC. At 28oC they have nicked wings and show a bb-like phenotype, having small bristles, slow development and cuticular defects. Ybbts1; vgunspecified/+ flies have nicked wings at 22oC.
