Fig 3. Polymorphism of HMS and SRD genes in D. albomicans.

Males and females from inbred lines of D. abomicans (alb2, shl2) and D. nasuta (nas3) were tested for fertility and sex ratio using the exhaustive mating protocol, so were the F1 males and female from the crosses (♀ × ♂) among these three lines. Virgins from alb2 were used as testers throughout (Materials and Methods). Box plots of male fertility (A) and offspring sex ratio (B), female fertility (C) and offspring sex ratio (D). Phenotypes not sharing the same numerals (1–4) in each panel are significantly different (P < 0.05, ANOVA and TukeyHSD). The sample sizes are shown above the abscissa.
