Figure 2From: Dynamics of genetic variability in Anastrepha fraterculus(Diptera: Tephritidae) during adaptation to laboratory rearing conditionsHeterozygosity ratios (Ln RH) between generations n and n+6 for CL (A) and TW (B) populations. Dashed lines represent the 95% confidence interval of the normal distribution. Positive and negative Ln RH values denote an increase or a decrease in variability through time, respectively.Back to article page
