From: Parallel reduction in expression, but no loss of functional constraint, in two opsin paralogs within cave populations of Gammarus minus (Crustacea: Amphipoda)

Figure 4

Comparisons of opsin expression in sister pairs of surface and cave populations. A. Average relative expression of Ops1 to 18S as measured by qRT-PCR (n = 20 individuals per population). B. Average relative expression of Ops2 to 18S as measured by qRT-PCR (n = 20 individuals per population). Error bars depict standard error of the mean. All comparisons between sister populations were statistically significant (P < 0.01, nested ANOVA, Table 3), indicating a reduction in opsin expression in the cave populations.
