Fig. 4.—

An illustration of parallel gains of new introns at a single locus, Dpul_327924. At this locus, six nonhomologous neointrons were inserted at the same site in six separate evolutionary events. Distinct alleles bearing nonhomologous introns are highlighted with distinct colors. A phylogeny for the alleles bearing the six nonhomologous neointrons was generated by the neighbor-joining method using exon sequences only. Branches with greater than 80% bootstrap support are labeled on the tree. cDNA sequences are indicated by green bracket in the sequence alignment. Further details are available in supplementary fig.
