origin: Recovered among progeny of cold-treated fly.
discoverer: Gottschewski 34c.
references: 1935, DIS 4: 7, 14, 16. 1937, Z. Induktive Abstammungs-Vererbungslehre 73: 131-42. 1937, DIS 8: 12.
phenotype: Veins irregularly thickened, especially toward tips, which are usually deltas and fused broadly to marginal vein. Stronger expression in males than in females. Co/N8 wild type except for slightly thicker L3 vein. Co/Ax like Ax/+. RK1A.
cytology: Associated with a tandem duplication, Dp(1;1)Co = Dp(1;1)3C4-5;3D6-E1 (Schultz, 1941, DIS 14: 54-55). Result of duplication of 3C7, deficiency for which gives Notch (Morgan, Schultz, and Curry, 1941, Carnegie Inst. Wash. Year Book 40: 283).
other information: Reversion to wild type occurs in Co/Co by unequal crossing over. A member of the Notch pseudoallelic complex.
