Comparison of the sequence divergence of junction Alus and internal Alus in distinct duplication pairs. The six duplication pairs are: 1, chr1:466-30596(-) and chr2:114046769-114076456(-); 2, chr1:487-30596(+) and chr9:845-30515(+); 3, chr2:114046769-114076720(+) and chr15:100307957-100338402(+); 4, chr2:114046769-114069083(-) and chr19:11002-33344(+); 5, chr9:437-30515(-) and chr15:100307957-100338529(-); 6, chr9:8507-30515(+) and chr19:11002-33344(+). AluJo, AluJr, AluSp, AluSx, AluYc are the internal Alus in the duplication pairs.
