According to a study from Guelph, Canada, "DNA barcoding-sequencing a standard region of the mitochondrial cytochrome c oxidase 1 gene (COI)-promises a rapid, accurate means of identifying animals to a species level. This study establishes that sequence variability in the barcode region permits discrimination of 98% of 201 fish species from the Canadian Pacific."
"The average sequence variation within species was 0.25%, while the average distance separating species within genera was 3.75%. The latter value was considerably lower than values reported in other studies, reflecting the dominance of the Canadian fauna by members of the young and highly diverse genus ...
