location: 2-6.1 (removed from In(2L)Cy and located by Tinderholt).
discoverer: L. Ward, 20c.
references: 1923, Genetics 8: 276-300 (fig.).
phenotype: Wings curled upward; rarely overlaps wild type at 25o, but frequently overlaps at 19oC. Curvature caused by the unequal contraction of the upper and lower epithelia during the drying period following emergence from the pupa case (Waddington, 1940, J. Genet. 41: 75-139). Classifiable in single dose in triploids. Usually homozygous lethal, but may emerge as dwarf with more extreme wing character. RK1A.
cytology: Ordinarily inseparable from In(2L)Cy = In(2L)22D1-2;33F5-34A1, although it has been separated by Tinderholt (1961, DIS 35: 47).
other information: Cy removed from In(2L)Cy still causes a local reduction in crossing over in the ed-c1 region (Sederoff).
