Calculated values from the similarity index for the ascidian species in the study.

Part A of the table is for the ascidian species from SBYH. The species are sorted according to the values in the Average Bands/Marker row. Species which have higher numbers of average bands per marker have a higher degree of similarity and therefore lower levels of polymorphism. Part B contains the information from the Ventura C. savignyi and C. intestinalis populations.
