Figure 3

Average amplitude ratio histograms for O. nubilalis populations. Frequency distributions of average sensillum amplitude ratios combined from crosses shown in Figure 2. Each histogram depicts the sum of all individuals expected to carry specific genotypes according to the sex-linked hypothesis (see Figure 2 for separate populations): A) X^EX^E B) X^ZX^Z C) X^EX^Z D) X^EX^E + X^EX^Z and E) X^ZX^Z + X^EX^Z. Bottom figures show previously published data from F) Cossé et al., 1995 [13] and G) Hansson et al., 1987 [11]. Note the different x-axis scale in histograms F) and G).
