norpA << bk1 << lac << bi << bk2 << rb << bk3
Breakpoint(s) molecularly mapped
Translocation breakpoint hits lac and bi.
Limits of break 1 from polytene analysis (FBrf0051990) Right limit of break 2 from complementation mapping against rb (FBrf0051990) Limits of break 3 from polytene analysis (FBrf0051990)
Phenotypic data suggests extensive overlap of gene function in the region of the bi locus.
