Comments on Cytology

The deficiency causes a characteristic alteration in the polytene cytology, such that 3C7, fused to 3C6, cannot be independently resolved.

(Welshons and Welshons, 1986)

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

    Eye color strawberrylike (but more mottled) and eye surface rougher than in faswb62b (= swb62b of Ives, 1969, DIS 44: 46).
