T(Y;2)L&S_set1

Set of Y;2 translocation stocks designed to allow generation of aneuploid animal by crossing two members of the set with breakpoints flanking the region of interest. For most regions, animals carrying both the duplication and the deficiency of the region between the autosomal breakpoints can be recovered and unambiguously identified.

23F to 25A is inverted.

(Lindsley et al., 1972)

23F to 25A is inverted. Break at 25A is described as 25F in the text but as 25A in the table.

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.
