Fig 3. STRUCTURE analyses of five pairs of sympatric Fucus populations.
Populations D1, E1, F1, V1 and W1 are F. radicans while D2, E2, F2, V2 and W2 are F. vesiculosus. Analyses are based on genetic variation in 9 microsatellite loci. Vertical bars indicate assignment probability for each genet to any of two genetic groups (K = 2). Left side of the panel are analyses with the software option LOCPRIOR, while right side are without LOCPRIOR.
