Unique and repeated l -mers. A and G: unique l-mers; B and F: individual repeats; C, D, E, and H: common repeats where C and E contain repeats only for one of the genomes, D contains repeats for both genomes, and H contains l-mers that are common to both genomes. Note that$n_1^{\mathrm{dist}}=A+B+C+D+E+H$ ,$n_2^{\mathrm{dist}}=C+D+E+F+G+H$,$n_1^{\mathrm{uniq}}=A+E+H$,$n_2^{\mathrm{uniq}}=G+C+H$, n^dist = A + B + C + D + E + F + G + H and n^uniq = A + G.
