Figure 2: Dollo parsimony based phylogenetic analysis using introns as phylogenetic informative markers. The observed phylogenetic incongruencies are represented with red markings. Considering the fact that intronic positions were used in the Dollo parsimony analysis, it is not surprising to observe monophyletic groupings of the intron less genes (boxed in blue rectangles). Surprisingly, the analysis could successfully resolve the phylogenetic relationship between mitochondrial and CYP2 clans (marked with dotted line green color boxes).
