  1. Grapevine, cacao and peach coloured independently; the ranges of the coloured regions determined by inspection of the self-comparison dot-plots; for the first two, these correspond as closely as can be determined to the ranges displayed in [1] and [3]. The other four genomes are coloured according to homologies with the first three. Peach ranges are more difficult to distinguish than those of grapevine and cacao, accounting for the somewhat elevated number of blocks of different colors, and this ambiguity is projected via the coloring process onto strawberry and poplar.
