Genetic mapping information
Comments

Breakpoint 2 was mapped to a HindIII-XbaI restriction fragment. The position of the restriction fragment on the reference sequence was inferred by a FlyBase curator.

Comments on Cytology

Limits of break 1 from polytene analysis (FBrf0047852) Left limit of break 2 from complementation mapping against hb (FBrf0047852) Right limit of break 2 from polytene analysis (FBrf0047852)

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 exhibit an hb- phenotype. Phenotype is not due to position-effect variegation as there is little variability in the phenotype.
