Comments on Cytology

Genetic data indicate that the mutation is associated with a reinversion of the BM2 inversion. BM2 phenotype reverted.

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.

    In combination with other aberrations
    NOT in combination with other aberrations

    Incubation of wild-type male salivary gland chromosomes in haemolymph from In(1)fB15 males results in variegated morphology of the X chromosome.

    (Ghosh and Mukherjee, 1991)

    More extreme in combination with E(f). RK2A.

    The variegated morphology of the In(1)fB15 chromosome is suppressed in males derived from daunspecified/daunspecified mothers.
