FIGURE 2

Male discrimination in two differently exposed lines. Mean (±SEM) male courtship index to P-line (open bars) and M-line (green bars) target females. A pair of decapitated female flies (a P-line and a M-line female) was simultaneously presented to a single tester male, under red light, during a 5-min period. For each exposed line, Forced-line (A) and Choice-line (B), the male ability to discriminate and court the two target females is shown above each pair of bars (∗p < 0.05). (A) N = 32 (B) N = 56–65.
