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

    Mutants exhibit missing alulae (D phenotype) and shortened wings with close crossveins and widely spaced posterior scutellar bristles (ds phenotype). Mutants also exhibit a smaller body and wings than expected.

    (Craymer, 1980)

    body small. Homozygous lethal and lethal over D3 though not over D1 (Carpenter, 1993, pers.comm); T(2;3)D4/dsW shows mutant characteristics of dsW/dsW.
