Discriminant analysis of principal components (DAPC).

<p>Two linear discriminants (LD1 and LD2) were used, following selection of principal components using a-score optimization, to plot <i>T</i>. <i>brucei</i> individual isolates. Dots represent individual genotypes connected by a line to the center of an ellipse with different colors representing the three clusters; blue (cluster 1), red (cluster 2), and purple (cluster 3).
