The sizes of the larval body and the organs dissected from mutant larvae were compared with those of mature third-instar Oregon-R larvae and estimated according to an arbitrary scale: 1.0, strongly reduced size (≤50%); 2.0, reduced size (50 to 90%); 3.0, normal size (90 to 110%); 4.0, increased size (110 to 150%); and 5.0, strongly increased size (≥150%). The average values are indicated. Abbreviations: E/A, eye-antenna disc; H, haltere disc; L1, L2, and L3, first, second, and third pairs of leg discs, respectively; W, wing disc.
