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

    Generates reversed acrocentric compound X chromosomes in Dp(1;1)BSRAG/+ female, usually by a double exchange in which one exchange occurs between the duplicated segment of one strand and the homologous region of its sister and the other between the duplication-bearing X and its normal homolog. Rate of C(1)RA generation about 6 x 10-4.
