Many early studies of ribosomal RNA gene (rDNA) suggested that rDNA tandem repeats within species are homogeneous. However, increasing number of reports have found intra-individual rDNA polymorphism across a range of taxa. Here, we reported a high level of intra-individual polymorphism of 18S-ITS1-5.8S rDNA in the genome of Cynoglossus melampetalus (Pleuronectiformes Cynoglossidae), indicating a non-concerted evolution manner. Sequence alignments found two distinct types of 18S and 5.8S (Type A and and five type
