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

    Homozygotes survive until third larval instar.

    (Kuzin et al., 1994)

    Suppresses the extra sex comb phenotype of Pc4, Ts(YLt;2Lt)L124. Causes between 50% and 100% suppression of the Pc4/+ extra sex combs phenotype.

    (Kennison and Tamkun, 1988)

    dominant; suppresses extra sex combs in Pc4/+
