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.

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.
    Phenotypic Data
    In combination with other aberrations

    Heterozygotes with Df(YS)B4 are sterile.

    (Gatti and Pimpinelli, 1983)
    NOT in combination with other aberrations

    Chromosome is male sterile in the absence of an extra Y chromosome.
