(A) Parental species mean genome size. *: P value < 0.05; **: P value < 0.01; ***: P value < 0.001 (Wilcoxon rank sum test W significant differences between species and sexes). (B and C) Mean genome size for parental species and all hybrid generations (gray bars) compared with theoretical mean values (red line) for female (B) and male (C) samples. Dbu: D. buzzatii; Dko: D. koepferae. Error bars represent standard error. *: P value < 0.05; **: P value < 0.01 Not useful (Wilcoxon signed-rank test V significant differences comparing experimental measures with the theoretical value).
