Genetic mapping information
Comments

Breakpoint(s) molecularly mapped

(Bargiello and Young, 1984)

3B1-2 breakpoint is approximately 100 kb distal to the wa copia insertion point (Pirrota, Hadfield and Pretorius, 1983, EMBO J 2: 927-34; Reddy et al., 1984).

Comments on Cytology

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

    T(1;4)JC43/Ts(1Lt;4Lt)JC43+Ts(1Rt;2Rt)RC45 flies have a variable circadian rhythm phenotype; either a very long-period rhythmicity, or rhythms that grade into arrhythmicity.

    (Smith and Konopka, 1981)
    NOT in combination with other aberrations

    Rhythmic.

    (Bargiello et al., 1984)

    male lethal.
