Genetic mapping information
Comments

Breakpoint 2 was mapped to a HindIII-XbaI restriction fragment. The position of the restriction fragment on the reference sequence was inferred by a FlyBase curator.

(Bender et al., 1988)

Breakpoint(s) molecularly mapped

(Bender et al., 1988)

+60. DNA coordinates from 85A map (Jones and Rawls, 1988, Genetics 120: 733-42) ('+' values to right, '-' values to left or centromere end of map). Proximal breakpoints of deficiencies 5, 16 and 19; distal breakpoint of deficiency 25

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

    Fails to complement Df(3R)D8. Lethal in combination with Df(3R)p5.

    (Jones and Rawls, 1988)

    Dp(3;3)D1 / Df(3R)p25 heterozygote is lethal.

    (Duncan, 1986)
    NOT in combination with other aberrations

    Dominantly causes tergite defects in less than 50% of run3 heterozygotes.

    (Duffy et al., 1996)

    Homozygotes exhibit an hb- phenotype. hbb1/Df(3R)p25 heterozygotes exhibit anterior deletion of the labial segment and the three thoracic segments and a posterior deletion of the posterior portion of A7 and the anterior portion of A8.

    (Bender et al., 1988)

    Homozygotes for the double mutant ftz10 Df(3R)p25 die as very abnormal embryos that have only three setal belts.
