Figure 1From: The role of transposable elements in the evolution of non-mammalian vertebrates and invertebratesNon-mammalian vertebrate and invertebrate genomes have lower levels of TEs than mammalian genomes. Evolutionary trees for chicken [30], zebrafish, sea squirt [62], Drosophila [63] and worm [63]. Percentages of TEs in each genome are shown on the right.Back to article page
