phenotype: Eyes of L2/+ as small as or smaller than L/L (L = lobe: heterozygous L eyes slightly smaller, with nick in anterior edge, and lower half of eye reduced more than upper; overlaps wild type; homozygous L eyes much smaller and less variable). L2 homozygotes have tiny eyes and are poorly viable or completely lethal, depending on background. Best used as heterozygote. Eyes further reduced in combination with M(3)w, M(3)h33j, and M(2)12 (Dunn and Coyne, 1935, Biol. Zentr. 55: 385-89). Classifiable in single dose in triploids (Schultz, 1934, DIS 1: 55). Reduced number of cells enter into formation of eye disks (Steinberg, 1944, Proc. Natl. Acad. Sci. U.S. 30: 5-13). RK1 as heterozygote.
