Genetic mapping information

Breakpoint(s) molecularly mapped

3A3-4 (left or distal) breakpoint localized to an approximately 4-kb restriction fragment 2-6 kb to the left of the origin of a 160-kb walk in the vicinity of z (Gunaratne, Mansukhani, Lipari, Liou, Martindale and Goldberg, 1986, Proc. Nat. Acad. Sci. USA 83: 701-05)

Comments on Cytology

Removes the entire 3B interval.

Left limit of break 1 from polytene analysis (FBrf0023906) Right limit of break 1 from inclusion of tko (FBrf0023906) Left limit of break 2 from inclusion of w (FBrf0023906) Right limit of break 2 from polytene analysis (FBrf0023906)

    In combination with other aberrations

    Df(1)w-rJ1/Df(1)wm4L rst3R viable Df(1)w-rJ1/Df(1)wm4L rst3R w phenotype Df(1)w-rJ1/Df(1)wm4L rst3R females display reduced crossing over and increased nondisjunction for all pairs of homologues.

    NOT in combination with other aberrations

    Heterozygotes with gt13z and gtE6 have reduced viability and the few adult escapers have a normal phenotype.

    Notes on Origin

    Regular product of unequal exchange between 3C1-2 (or 3) of a wa, wa2, or wrdp chromosome and the 3A or 3C-D region of a specific homologue.
