Relationship between segmental duplication pairs in the human genome. The relationships are shown between the 10 duplication pairs where the miR-1302 genes located on chromosomes 1, 9, 15 and 19 are linked by green lines. The four copies of hsa-mir-1302-2 are distributed on chromosomes 1, 9, 15 and 19. Hsa-mir-1302-3 is on chromosome 2. The circular ideograms of the chromosomes were drawn using the files of genome karyotypes from the UCSC Genome Browser.
