The preliminary study of rDNA polymorphisms in P. monodon showed that inter- and intraindividual polymorphisms of rDNA were clearly observed in this species. Individual-specific rDNA restriction patterns were observed when digested with BamHI and SacI. The intergenic spacers (IGS) region of P. monodon rDNA plays an important role in length heteroplasmy at both between- and within-individual levels in this species.
