Figure 4From: Isolation with differentiation followed by expansion with admixture in the tunicate Pyura chilensisGenetic differentiation against geographic distance for COI haplogroups and EF1a haplotypes of Pyura chilensis. Linearized genetic differentiation and geographic distance for the following data: ALL COI, COI HG1, CO HG1 grouping the five northern sites, COI HG2, all EF1a, and EF1a excluding LM.Back to article page
