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

    In(1)l-v231 males carrying the free duplication Dp(2;f)e97 show 58% viability relative to controls.

    (Berloco et al., 2014)

    The autosomal heterochromatin in Dp(2;f)e97 appears to suppress the eye colour variegation phenotype of In(1)wm4.

    (Berloco et al., 2014)

    The autosomal heterochromatin in Dp(2;f)e97 appears to suppress the eye colour variegation phenotype of In(2)bwVde2.
