Table 2.
Mitochondrial introgression across the flat periwinkle samples included in this study indicated as the number (and percentage) of individuals from one species carrying mitochondrial typical haplotypes from the other species. Codes are the same as in Table 1. Individuals were classified into species using morphology and nuclear markers except for those marked witha
