MOTIVATION Segmental duplications are common in mammalian genomes, but their evolutionary origins remain mysterious. A major difficulty in analyzing segmental duplications is that many duplications are complex mosaics of fragments of numerous other segmental duplications. RESULTS We introduce a novel measure called duplication distance that describes the minimum number of duplications necessa...
