Comments on Cytology

Though cytologically invisible with the light microscope, in the EM only the 10A4-5 band proximal to 10A1-2 is seen i.e. 10A3 cannot be seen. It is not possible to distinguish between the various possibilities that the interband between 10A1-2 and 10A3, plus, or minus, some, or all, of 10A3 has been deleted.

(Kozlova et al., 1994)

Left limit of break 1 from polytene analysis (FBrf0073632) Right limit of break 1 from inclusion of sev (FBrf0073632) Left limit of break 2 from inclusion of ms(1)10A (FBrf0073632) Right limit of break 2 from non-inclusion of Hsp60 (FBrf0073632)

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.

    NOT in combination with other aberrations

    Transheterozygotes with slm10AG102 show a very small degree of slm mutant phenotype.

    (Kozlova et al., 1994)

    Adult eyes are slightly rough, R7 is missing from each ommatidium of the eye.
