Consensus trees showing maximum likelihood ancestral state reconstructions of diploid numbers based on the Mk1 model using the Mesquite software. This evolutionary analysis integrated cytogenetic data available for Doradidae species (including the present study) and two Auchenipteridae species (sister group) with sequences of two mitochondrial DNA fragments (COI and 16S) and one nuclear DNA fragment (Rag 1) obtained from the molecular phylogeny of Sabaj and Arce (2022)
