Examples of increased TE density. The figure presents the comparative bovine/human/mouse map for a segment of HSA10. a) Alu density is increased in the human genome in the vicinity of an HSA breakpoint. b) Alu density is increased in the mouse genome, in the vicinity of a MMU breakpoint. c) No repeat density increase is observed in the human or mouse genome in the vicinity of a BTA breakpoint region. d) Alu density is increased in both human and mouse genomes in a MMU breakpoint, probably due to the strong correlation observed between the local SINE density in mouse and the Alu density in orthologous loci in man.
