Phylogenetic tree from molecular data of some species of Trachinotini tribe (a), adapted from Reed et al. (2002). The molecular relationship is confronted with the chromosomal formula of the Trachinotus species analyzed. Schematic illustration shows the role of additional pericentric inversions leading to new acrocentric chromosomes and modification of the FN value (b), and the derived condition of multiple sites of 18S and 5S rDNAs in Trachinotus goodei (c).
