Genetic mapping information
Comments

Breakpoint(s) molecularly mapped

(Schweisguth and Posakony, 1992, Scott et al., 1983)

Breakpoint 3 maps within an intron of Antp but closer to the upstream exon; the breakpoint is proximal to In(3R)AntpRM and distal to the In(3LR)AntpWu breakpoint.

(Jorgensen and Garber, 1987)

Third-chromosome breakpoint 165-166 kb distal to proximal breakpoint of Tp(3;3)Dfdrv3.

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

    Recessive lethal. Heterozygotes show transformation of dorsal head structures into dorsal thoracic structures and, occasionally, transformation of antennae into legs.
