Affected Genes Inferred by Location (0)
    If no genes are listed here, it may be because the affected region is very large. The JBrowse insert above may show an error for the same reason, and other FlyBase tools such as CytoSearch may also fail for large regions. You can contact FlyBase for more help.
    In these cases, there will be no "Export to Hitlist" button to the left.
    Phenotypic Data
    In combination with other aberrations

    One copy of Df(3R)ex56 enhances the mild transformation of the basal capsule of the arista seen in Df(3R)ss-D114.4/+ flies.

    (Emerald et al., 2003)
    NOT in combination with other aberrations

    Df(3R)ex56 heterozygotes do not exhibit any size alterations or roughness in eyes when compared to control adults.

    (Hoang et al., 2010)

    76% of homozygous Df(3R)ex56 mutant embryos show nervous system defects. Homozygous embryos also show failure of germ band retraction. Only about 50% of the homozygous Df(3R)ex56 animals reach the adult stage, and the survivors live just for a few days.

    (Suzanne, 2004)

    Homozygous viable. The third antennal segment is reduced in size in homozygous flies and develops ectopic bristles. The basal cylinder of the arista is enlarged and produces bracted bristles. Homozygous clones result in partial transformation of the basal cylinder towards leg; it is segmented and has bracted bristles.
