location: 4-2.0 (located in diplo-4 triploids by Sturtevant, 1951, Proc. Natl. Acad. Sci. U.S. 37: 405-7).
origin: Spontaneous.
discoverer: Hoge, 14e.
references: 1915, Am. Naturalist 49: 47-49.
Bridges, 1935, Biol. Zh. (Moscow) 4: 401-20 (fig.).
phenotype: Eye reduced to three-fourths to one-half normal area, but varies from no eyes to extensive overlapping of wild type. Less extreme at low temperatures. Optic ganglia reduced (Richards and Furrow, 1922, Proc. Oklahoma Acad. Sci. 2: 41-45). Variability in size of eye affected by environmental and genetic conditions (Morgan, 1929, Carnegie Inst. Wash. Publ. No. 399: 139-68; Baron, 1935, J. Exptl. Zool. 70: 461-90). RK2.
cytology: Placed between 102C15 and 102E10 on basis of the absence of ey+ from the 2LD4P element of T(2;4)b = T(2;4)25E;102C15-D1 (Morgan, 1946, DIS 20: 88) and its presence on Df(4)11 = Df(4)102E2-10;102F2-10 (Hochman).
