Figure 3From: Isolation with differentiation followed by expansion with admixture in the tunicate Pyura chilensisGenetic structure of EF1a SNPs of Pyura chilensis. A) Relative frequencies per locality of 9 polymorphic SNPs, each “column” represents a locus and the bands of different grey shades correspond to the relative frequency of alleles; B) Genetic composition of individuals inferred from Bayesian clustering analysis. Best fit of data with k = 3 (Additional file 1: Figure S1).Back to article page
