        campaniform sensillum of proximal dorsal radius

        microchaeta & scutellum

        microchaeta & scutum

        sense organ & wing vein

        Detailed Description
        Statement
        Reference

        acHw-685/Df(1)sc19 generates lateral clusters of microchaetae on the scutellum and promotes differentiation of extra sensilla campaniformia on the dorsal radius of the wing, of microchaetae or other sensilla on wing vein 3 and occasional microchaetae on wing vein 2. Slight increases in numbers of microchaetae on notum as well. Displays a very weak ac effect despite presumed homozygous deficiency for ac.

        Claimed to be associated with terminal deficiency, Df(1)yT1b-685, which was broken at 45.4 kb to 43.9 kb. That this determination may be in error is suggested by the observations: (1) that no other terminal Df(1)yT1b-, including two others broken in the same restriction fragment, shows a Hairy-wing effect; (2) terminal deficiencies induced in mu2 females are unstable losing about 75 base pairs per generation (FBrf0047919), yet acHw-685 appears to be stable and (3) acHw-685 does not appear to be completely deficient for ac.
