Scientific ""dogmas"" are conjectures that must be subjected to critical tests. It is generally accepted that mitochondrial DNA (mtDNA) does not recombine although several recent examples challenge this dogma. An incongruence of mitochondrial and nuclear genome phylogenies points to hybridization. Hybrid individuals offer the possibility of studying mtDNA recombination. During a study of codfish genomics, we have come across a case of potential recombination of widely separated mitochondrial DNAs. Is it real or an artifact of the method? We discuss the evidence for mitochondrial differences among the taxa in light of the whole genome nuclear differences.
