Figure 3From: Rapid speciation in a newly opened postglacial marine environment, the Baltic SeaAllele frequency distribution of microsatellite loci. Each circle represents an allele and its frequency is proportional to the size of the corresponding circle (red: F. radicans, yellow: F. vesiculosus in Öregrund, SW Gulf of Bothnia; blue: F. vesiculosus in all other populations).Back to article page
