Figure 8.

The combined PCA of 100 kb fragments (n = 3399) of three Dm data sets based on hexamers. The three data sets used are: the original sequence (□), the Tandem Repeats Finder masked sequence (▽) and the RepeatMasker masked sequence (*). Chromosomal origins of the fragments are indicated by colour (black = X, yellow = 2, blue = 3 and red = 4).
