Figure 1. Met and SRC mRNA levels in D. magna over two consecutive 72-hr molt cycles.

Each time point was normalized to the initial 0-hour time point. Data are presented as mean and standard deviation (n = 3). Data points connected by a thick horizontal bar are not significantly different but are significantly different from the adjoining data point (P < 0.05, ANOVA). Shaded regions denote the periods of embryo susceptibility to male sex determination by methyl farnesoate.
