Viability about 90 percent wild type. Females sterile. According to Beatty [1949, Proc. Roy. Soc. Edinburgh, B 63: 249-70 (fig.)], oocytes often misshapen, eggs abnormal in appearance, and parovaria nearly always absent. RK2.
cytology: Salivary chromosome studies by Demerec and Sutton show locus to lie between 7C4-5 and 8C1-2 (Demerec, Kaufmann, Fano, Sutton, and Sansome, 1942, Carnegie Inst. Wash. Year Book 41: 191). Further restricted to 7E1 through 8C2, on the basis of its exclusion from Df(1)sn = Df(1)7B2-3;7D22-E1 (Hinton and Welshons, 1955, DIS 29: 125-26).
