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.

    In combination with other aberrations
    NOT in combination with other aberrations

    Ts(1Lt;YSt)W27+Ts(1Rt;YLt)V24/0 males show individualisation defects in the testes. The testes contain nuclei scattered throughout the spermatid bundles. The scattered single nuclei are needle shaped. A small number of individualisation complexes (ICs) are located with aligned nuclear bundles, but most of the ICs are disrupted. The dispersed ICs are fragmented and distributed along the elongated spermatid bundles. They are cone shaped, with the blunt end pointing apically and the pointed end directed basally. The isolated sperm heads often appear to trail the IC fragments.
