The FCA (axis 1 horizontal and 2 vertical) presents a very clear classification of the genotypes of the 27 analyzed samples into two clusters: domestic Atlantic at the left and wild Mediterranean at the right. Legend at the right uses the numbers from the first column of Table 1: R samples with small circles = river sample; H with small triangles = hatchery sample; large circles represent sea trout (st01), with Rhône River in red, Var River in green; unknown origin (X = Rhône or Var River) in grey. In circles are given the number of missing locus genotypes among 7.
