Lindsley & Grell, 1972, p. 112
origin: Spontaneous in stock containing y and never separated.
discoverer: Bridges, 23c12.
references: Neel, 1941, Genetics 26: 52-68 (fig.).
phenotype: Male has extra bristles along wing vein, on head (especially occipitals), and on thorax. Also, extra hairs on wing veins, back of head, and mesopleurae. Homozygous female sterile, expression more extreme than male, and has 40-80 percent wild-type viability. Heterozygous female has good viability. Phenotype similar to male. Classifiable in single dose in triploids (Schultz, 1934, DIS 1: 55). Interacts synergistically with h and pyd (Neel, 1941). Suppressed by su(Hw) and su(Hw)2. RK1A as heterozygous female and as male.
cytology: Salivary chromosome analysis by Demerec and Hoover shows repeat for doublet 1B1-2, i.e., Dp(1;1)Hw (1939, Genetics 24: 68).
