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

    Inferred to overlap with: Df(1)16-1-88.

    (Munoz, 2004.1.5)

    Deficiency heterozygotes between Df(1)B12 or Df(1)LB6 and Df(1)R21, Df(1)16-2-13 or Df(1)DCB1-35c are viable, fertile and do not display any visible phenotype.

    (Prud'homme et al., 1995)
    NOT in combination with other aberrations

    Cell viable in cuticle.

    Notes on Origin
    Discoverer
     

    Separable from: flam2G. flam2G has been extracted by recombination from the Df(1)B12 chromosome, indicating that in contrast to previous conclusions (FBrf0080334), Df(1)B12 does not affect the flam locus.
