Tailless retropseudogene presence/absence alignments for primates. In the alignments of orthologous loci for M1-M9 markers (one or several with tailless retropseudogenes and one or more orthologous loci without tailless retropseudogenes) all direct repeats are boxed and priming sites are shaded. The nonorthologous, most closely related tRNA species is given in the last line of each of the nine alignments. Hyphens represent gaps in the sequences. Homo sapiens (Hs); Pan troglodytes (Pt); Gorilla gorilla (Gg); Pongo pygmaeus (Pp); Hylobates lar (Hl) for Hominoidea; Macaca mulatta (Mm) for Cercopithecoidea; Lagothrix lagotricha (Ll) for Platyrrhini; Lemur catta (Lc) for Strepsirrhini. Accession nos. or internal reference numbers are shown in bold.
