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.

    Other Comments
     

    Group D' deficiencies have been generated from the progenitor genotype of C(2L)RM-SH3 in combination with C(2R)RM-SH3 and C(2L)RM-SH3 in combination with C(2R)RM-VK1.

    (Hilliker and Holm, 1975)

    Eleven such deficiencies recovered.
