Table 1 Overview of gene retrotransposition analysis for eight vertebrates
From: Analysis of the role of retrotransposition in gene evolution in vertebrates
Species | Number of genes * | Number of PRs | PR matches retrotransposed TE ** | PR overlaps pseudogene annotation | FLE ≤ 0.8 *** | Number of retro- pseudogenes (RψGs) | PRs passing local gene order test | Matching Refseq mRNA or Unigene consensus **** |
