RpL38⁻/+ andRpL5⁻/+ wings are abnormally large because of increased cell size

Nineteen female wings from the control genotype and 10 female wings from the mutant genotypes were analyzed; all figures are reported to three significant figures. P-values were calculated using a two-tailed Student's t-test assuming equal variances: *P < 0.05, **P < 0.01.

^aThe area of the whole wing exclusive of the alula and costal cell was measured.

^bEach wing-blade cell protrudes a single hair; wing hairs were counted in an area of 40,000 pixel² (∼15,000 μm²) from the middle of the region flanked by vein IV, vein V, the posterior cross-vein, and the wing margin.

^cReciprocal of the mean cell density.

^dEstimated by multiplying the mean wing area by the mean cell density.

^eControl genotype was the w¹¹¹⁸-iso strain; all other mutants were crossed into this background.
