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

    The severity of the T(2;3)BTD71/+ wing phenotype is dominantly enhanced by Df(3R)Exel6159; the proportion of flies that show withering at the posterior of the wing is increased.

    (Hartl et al., 2008)
    NOT in combination with other aberrations

    3.8% of heterozygotes have a wild-type wing phenotype, 76.9% show a noticeable loss of tissue at the posterior of the wing and 19.2% show withering at the posterior of the wing.

    (Hartl et al., 2008)

    T(2;3)BTD71/+ flies typically show a slight loss of tissue at the posterior of the wing.

    (Hartl et al., 2008)

    Isolated as disrupter of transvection at the BX-C, assayed with the phenotype of Ubx1:Cbx-1/+.
