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
    NOT in combination with other aberrations

    Df(2L)J4b flies show similar mortality levels to wild-type flies in response to feeding with both the ROS-resistant KNU53775 yeast strain and a standard yeast strain (W303).

    (Ryu et al., 2006)

    More than 99% of homozygotes do not survive to adulthood. The few adult escapers have no obvious morphological abnormality.
