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

    When heterozygous with In(2R)bwVK viability is increased. The bw+ cis-effect in different inversion chromosomes is ranked: In(2R)bwVDe1 > In(2R)bwVDe2 > In(2R)bwVK.

    (Koryakov et al., 1998)

    In(2R)bwVDe1/bw5 lethal

    NOT in combination with other aberrations

    homozygous lethal in embryonic stage <up>e.g., In(2R)bwDe2 (Tsai, 1955, Genetics 40: 601)</up>. Eye color variegated brown and red; extreme dominant brown with pebbled wing. homozygous lethal
