Alignments of the mitochondrial genes

The 13 proteins and the two rRNAs across the species of the build, aligned with MAFFT

One species at a time

Every species page has a Downloads section with its FASTA and GenBank record from NCBI, all its statistics as JSON, and its region composition as CSV, at /species/<name>.json and/species/<name>.csv.

For the sequences of several species, filter the species list and choose "FASTA of these rows": the genomes come from NCBI as one file.
