Figure 2

Results of the separate, normalised, whole chromosome PCA of the three genomes using hexamers. Chromosomes are colour-coded, as follows (according to the Dm numbering: black = X, yellow = 2, blue = 3 and red = 4). L and R stand for the left and right arms of the metacentric chromosomes, respectively. (A) Score plot (R2 = 0.97) of the Dm analysis. (B) Loading plot of the analysis in (A). (C) Score plot (R2 = 0.99) of the Dy analysis. (D) Loading plot of the analysis in (C). (E) Score plot (R2 = 0.92) of the Dp analysis. (F) Loading plot of the analysis in (E). The colouring of the hexamers in (B), (D) and (F) is proportional to the A/T content. Pink is all A/T and blue is all G/C.
