Lineage-specific AluYb8 insertions. Four examples of gel chromatographs are shown. The locus designation is shown at right, while the product sizes for filled and empty alleles (pre-integration size) are indicated at left. The DNA template used in each reaction is listed at top. (A) Pygmy chimpanzee-specific AluYb8 insertion. (B) Common chimpanzee-specific AluYb8 insertion. (C) Chimpanzee lineage-specific AluYb8 insertion. (D) Gorilla-specific AluYb8 insertion.
