a, b, Repeat landscape of LINE (a) and LTR (b) of lungfish and axolotl. The two main peaks indicate there were two major LINE expansions in lungfish. The recent expansion (diverging ≤ 15% from the consensus sequences) contributed to 9% of the lungfish genome. The LTR landscapes are similar in these two species.
