Comments
Comments on Cytology

Deletion removes sequences extending from the big intron of psq to between the two promoters of lola.

(Berg, 1996.2.28)

Left limit of break 1 from polytene analysis (FBrf0086256) Right limit of break 1 from inclusion of psq (FBrf0086256) Left limit of break 2 from inclusion of lola (FBrf0086256) Right limit of break 2 from non-inclusion of lola (FBrf0086256)

    In combination with other aberrations

    Heterozygosity for Df(2R)Δ18 enhances the eye mottling phenotype (position effect variegation) seen in In(1)wm4h flies.

    (Schwendemann and Lehmann, 2002)
    NOT in combination with other aberrations

    Homozygous lethal.
