What the comparison shows
Genome
Genome size, GC content, strand skews and the lengths of the non-coding region, the D-loop, the rRNA and tRNA genes, with the taxonomy of each species.
Composition and genes
A/T/G/C bars for each region of the mitochondrial genome, and a gene-by-gene view of GC content, length and skews for the 13 protein-coding genes, both rRNAs and the D-loop. Every species keeps one colour and one marker shape throughout.
Codon usage and life history
The codons and amino acids whose usage differs most between the species you picked, then their maximum lifespan and other AnAge traits. For whole groups, see the statistics; for any feature across all 2,335 species, the plot.
