  Variations in mitochondrial genes are usually considered to infer
phylogenies. However some of these genes are lesser constraint than other ones,
and thus may blur the phylogenetic signals shared by the majority of the
mitochondrial DNA sequences. To investigate such effects, in this research
work, the molecular phylogeny of the genus Taenia is studied using 14 coding
sequences extracted from mitochondrial genomes of 17 species. We constructed
16,384 trees, using a combination of 1 up to 14 genes. We obtained 131
topologies, and we showed that only four particular instances were relevant.
Using further statistical investigations, we then extracted a particular
topology, which displays more robustness properties.
