Fig 3. Cultivated and wild type sorghum sample 2D projection using a PCA of their e_T-ratios.

Each sorghum accession, associated with e_T-ratios, can be seen as a point in a high dimensional space. This figure displays the projection of these points on the two first PCA axes using orange /blue dots to represent wild /cultivated individuals. The two first axes explain more than 30% of the original variability in all three cases.
