Presumed ancestral mitochondrial gene order based on a TreeRex analysis of each major clade of heterobranch gastropods. Grey boxes spanning multiple clades indicate the common Heterobranch gene order shared among most taxa. Empty white boxes represent missing genes from sequenced mitochondrial contigs. Tree topology is
