19 DIs of marker SNPs distinguishing marine and freshwater populations.

The divergence island IDs are in the format ‘chromosome number-DI number’. Asterisks denote DIs identified under the weak criteria; the remaining DIs are identified under the strong criteria. Bold font denotes regions identified in Refs 15 and 22 by the stringent criteria; non-bold font denotes regions identified in Refs 15 and 22 by less stringent criteria, and reported in supplementary materials for these refs. ns, number of nonsynonymous substitutions, sE, selection coefficient in favor of freshwater allele estimated from Lake Ershovskoye; sG, selection coefficient in favor of freshwater allele estimated from Quarry Goluboy.19 DIs of marker SNPs distinguishing marine and freshwater populations.
