Genetic mapping information

Left breakpoint 62-64 kilobases distal to the proximal breakpoint of Tp(3;3)Dfdrv3 (Scott, Weiner, Hazelrigg, Polisky, Pirrotta, Scalenghe and Kaufman, 1983, Cell 35: 763-76).

Comments on Cytology

Left limit of break 1 from polytene analysis (FBrf0034841) Right limit of break 1 from complementation mapping against Scr (FBrf0039012) Left limit of break 2 from complementation mapping against pum (FBrf0055853) Right limit of break 2 from polytene analysis (FBrf0034841)

    "84B;85C--D" was stated as revision. Cytogenetic, genetic and molecular analysis of Barker et al., (Genes Dev 6:2312--2326 ) and Kemphues et al., (Genetics 105:345--356 ) supports 85C location of the right break of this inversion as opposed to 84F.
