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

    Homozygous viable. Male and female heterozygotes exhibit a more extreme degree of interruption of wing veins than ci homozygotes.

    (Stern et al., 1946)

    Tp(4;2)ci+15/ci flies show L4 vein interruptions, whereas ci+/ci flies are wild type.
