Figure 2: Scatterplot output from a discriminant analysis of principal components (DAPC) for the genetic structure of Saccharina japonica individuals based on 19 microsatellites.

Dots represent individuals from the 28 populations, and different populations are depicted with different colours and symbols. Abbreviations correspond to populations presented in Table 1. The bar graph inset exhibits the variance explained by the two discriminant eigenvalues used for plotting. The 67% inertia ellipses are drawn for each population, representing the variance of the two principal components.
