bk1 hits noc << osp << bk2 << Adh

Genetic mapping information

Distal breakpoint hits noc.

Left and/or right breakpoints mapped to the DNA (Chia, Karp, McGill and Ashburner, 1985, J. Mol. Biol. 186: 689-706) Deleted for about 50 kb of DNA within both the osp and noc loci (McGill)

Comments on Cytology

Left limit of break 1 from non-inclusion of elA (FBrf0038047) Right limit of break 1 from inclusion of noc (FBrf0038047) Left limit of break 2 from inclusion of osp (FBrf0038047) Right limit of break 2 from non-inclusion of Adh (FBrf0087599)

In combination with other aberrations

Does not suppress the zeste phenotype in a z1 w11E4; Tp(1;2)TE35B homologue.

NOT in combination with other aberrations

Chromosome has no effect on the physical interaction between tandemly duplicated copies of w+ and z1, despite having breakpoints within the critical region.
