Boxplots of mutation rate ratios ($\mu$_m/$\mu$_n) of datasets of members of gastropod clades from the subclasses Caenogastropoda, Heterobranchia, Patellogastropoda, and Vetigastropoda. Median values (wide horizontal line in box of taxa with more than one dataset), interquartile ranges (boxes), minimum and maximum range (ends of whiskers that extend 1.5 times the interquartile range), means (solid square symbols), and outlier values (open circle symbols) are indicated
