Separate dotplot-like representations of Human chromosome 1 (X-axis) compared to equivalent chromosomes from several other mammalian species: (1) Pan troglodytes, (2) Macaca mulata, (3) Pongo abelii, (4) Gorilla gorilla, (5) Mus musculus, (6) Rattus norvegicus, (7) Bos taurus, (8) Canis familiaris and (9) Sus scrofa. Red colour indicates forward strand fragments and black the reverse strand ones. Plots indicate that there are closely-related (from 1 to 5) and remotely-related (from 6 to 9) sequences. This is caused by the fact of that chromosome numbering was based on their length and not their content. For example, human chromosome 1 is present in several chromosomes of Bos Taurus (but not in the first chromosome, as can be deduced from sub-figure 7). An image with the first five sub-plots projected over one sequence is provided in the Additional file 1
