discoverer: Bridges, 25kl6.
phenotype: Sex combs of male extremely large. Some distortion and shortening of legs. Wings show gap in vein L4 between posterior crossvein and margin. Wings slightly curved. Effects result from a combination of overgrowth and irregular folding of imaginal rudiments during the pupal period. Strong exaggeration in compound homozygotes with genes such as d, fj, ds, and ssa. Double heterozygote for cg and ci often shows gap in L4 (Waddington, 1952, J. Genet. 51: 243-58). Double heterozygote en cg/++ has slight degree of L4 interruption and thinning at low temperature. Triple heterozygote en cg/++; ci/+ has L4 interruption in half the flies (House, 1961, Genetics 46: 871). ciW interacts strongly with cg. cg/+; ciW/+ resembles ciW/ciW (House, 1953, Genetics, 38: 669-70). Females sterile. Oogenesis highly irregular (Beatty, 1949, Proc. Roy. Soc. Edinburgh B 63: 249-70). RK2.
