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).
