The architecture of mitochondrial chromosomes in 2,267 bilateral animals.

<p>The typical animal mitochondrial chromosome is represented as a single red color circle whereas multipartite chromosomes are represented as small circles. <i>Armadillidium vulgare</i> has a linear chromosome plus a circular chromosome. Numbers in brackets indicate the number of species for which entire genome sequences are known. Stars indicate partial mitochondrial genomes.
