Fig. 4

Haploid genome size across fish based on C-value. Boxplots representing C-values of 34 fish orders (top), organized by their taxonomic relationships (bottom). Y-axis represents C-values in log scale. For boxplots: horizontal bar, median; dashed lines, mean and standard deviation; circles, outliers. C-value for P. orbignyanus, red colored circle. C-value means represented by boxes colored from yellow (highest) to purple (lowest). Analysis of unpaired t-test of Pleuronectiformes versus each order are shown (****, P < 0.0001; ***, P < 0.001; **, P < 0.01; ns, not significant)
