WebCO1 Barcode Assay. The cytochrome c oxidase subunit 1 (CO1) gene is an ideal target for species discrimination as this gene is conserved across higher eukaryotes, including insects, fish, birds and mammals. CO1 is located on mitochondrial DNA, meaning it has a relatively fast mutation rate that aligns with speciation timescales. WebMaterials and Methods.
