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.

    Chromosome exhibits position effect variegation for bw. Homozygotes are partially viable. When adult flies do occur they are often deformed: small bristles, small eyes,

    Variegated in heterozygotes with bw+; strongly variegated in homozygotes and in heterozygotes with bw and other variegated browns. Homozygotes show melanotic clots of dried hemolymph.
