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

    Dp(1;2)y2A reduces the level of complementation that is normally observed between y1#8 and y2 (the progenitor of Dp(1;2)y2A), such that the body and wing cuticle of y1#8/Dp(1;2)y2A females has a more severe pigmentation phenotype than that of y1#8/y2 females.

    The presence of Dp(1;2)y2A increases pigmentation in both the body and wing cuticle in y1/y1#8 and y1#8/y1#8 females.

    Dp(1;2)y2A strongly increases pigmentation in both the body and wing cuticle in y1#8 hemizygous females.

    Hemizygous y1#8/Y males carrying one copy of Dp(1;2)y2A have dark pigmentation, while hemizygous y1#8/Y males carrying two copies of Dp(1;2)y2A have light pigmentation.
