Fig. 2From: Polymorphic duplicate genes and persistent non-coding sequences reveal heterogeneous patterns of mitochondrial DNA loss in salamandersMitochondrial gene rearrangements in Aneides hardii. a Aneides-specific mitochondrial gene order, which is ancestral for A. hardii. The region inferred to have been duplicated in the A. hardii-specific duplication event is underlined. b Inferred intermediate gene order after A. hardii-specific duplication event and the current novel gene order within A. hardii Back to article page
