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

    Dp(1;f)γ878/Dp(1;f)3A heterozygotes increases y+ expression, to 35% of full Dp(1;f)γ158 trans-suppression. y+ expression is quantitated in triple row bristles.

    (Donaldson and Karpen, 1997)
    NOT in combination with other aberrations

    Transmission rate through females to progeny is 55% in the first 5 days of egg lay.

    (Cook et al., 1997)

    Transmitted from meiosis at 27% in nod3/nod+ females and 52% in wild type females.

    Other Comments
     

    Minichromosome is 920bp in length.

    (Cook et al., 1997)

    Contains 600kb of centric heterochromatin in inverted orientation.

    (Donaldson and Karpen, 1997)

    Monosome transmission behaviour from both male and female parents is stable demonstrating normal transmission and normal centromere function.
