phenotype: Larval development 4 days longer than normal, resulting in giant larvae, pupae, and imagos. Adult weight 1.7 times normal. But not all genetically giant flies show the character; the rest have normal size. Distribution sharply bimodal. Percentage giant greatest in well-fed cultures; also raised by modifying action of bb11. Salivary gland chromosomes of double thickness in some cells (Bridges, 1935, J. Heredity 26: 60-64). RK3.
other information: Used by Bridges (1935) in the construction of salivary chromosome maps.
