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

    Seems to be poorly transmissible (Novitski, 1954). Produces a centric, single-ring-X and either an acentric, single-ring-X or a tandem, triple-ring-X chromosome by recombination between the two elements of the compound.

    the YL second arm had been replaced by the XP4D element of T(1;4)BS = T(1;4)15F9-16A1;16A7-B1;102F. A product of recombination between the duplicated BS second arm and the homologous region of the distal element of the tandem acrocentric.
