phenotype: Causes loss or marked reduction in number of scutelar, coxal, ocellar, first and second orbital, anterior notopleural, postvertical, tergital, and sternal bristles. Bristle patterns for sc through sc15 tabulated by Dubinin (1933, DIS 16: 70-70a; 1943, J. Genet. 27: 446). Bristle sockets missing; bristle cells absent 19 hr after pupation, when normally present [Lees and Waddington, 1942, Proc. Roy. Soc. (London), Ser. B 131: 87-l10]. Supressed by su(Hw) and su(Hw)2. RK1.
cytology: Placed in 1B3, on basis of its exclusion from Df(l)260-2 = Df(1)1B2-3, and its inclusion in the inverted section of In(1)sc8 = In(1)1B2-3;20B-D1 but not of In(1)sc4 = In(1)lB3-4;19F-20C1 (Muller and Prokofyeva, 1935, Proc. Natl. Acad. Sci. U.S. 21: 16-26; Demererec, Kaufmann, Fano, Sutton, and Sansome, 1942, Carnegie Inst. Wash. Year Book 41: 191; Sutton, 1943, Genetics 28: 210-17).
