Abstract

The taxonomy of the family Parodontidae is confused, with many open questions regarding the most appropriate generic groupings. Studies on the organization, structure, composition, and in situ location of chromosomal features have led to consistent advances in the understanding of genome evolution. Among the species of Parodontidae, the consistent chromosomal divergences can be helpful in taxonomic classification, such as heteromorphic chromosome sex, karyotypic formulae, and number/location of the repetitive DNAs. Molecular analysis of repetitive sequences of satellite DNA and their physical mapping in the chromosomes of different species in a single group may be used to infer evolutionary divergence and cladistic grouping. In the present study, rDNA and the satellite DNA pPh2004 were mapped by fluorescent in situ hybridization on the chromosomes of some species of Parodontidae. These results were analyzed and reviewed together with other chromosomal markers and previously published data, to formulate inferences about the diversification of the genomes and propose a clustering of some Parodontidae species. This analysis indicated that the species Apareiodon affinis, Parodon moreirai, Parodon hilarii, Parodon nasus, and Parodon pongoensis have an apomorphic state for satellite DNA pPh2004 in Parodontidae in relation to previously studied species of Apareiodon.
