(A) Distribution of mutant spot sizes observed on the wings of larvae (mwh/flr) treated with MNU at 2 mM (black bars), 6.7 mM (gray bars), and 0 mM (white bars). (B) Approximation curves of the spot size fitted by the polynomial approximation for the larvae treated with MNU at 2 mM (black line) and 6.7 mM (gray line). The mode of the spot size (solid arrows; 1.8 for 2 mM MNU and 2.2 for 6.7 mM MNU) and the average of the spot size (dotted arrows; 3.6 for 2 mM MNU and 4.1 for 6.7 mM MNU) for each dose were calculated from each polynomial approximation curve after the subtraction of the spot number without irradiation. (C) The relationship between the number of AO-stained clusters per wing and the mode of the spot size (solid lines) or the average of the spot size (dotted lines). The concentrations of MNU were 2 mM (black circles) and 6.7 mM (gray circles)
