| dna barcoding of clarias gariepinus, coptodon zillii and sarotherodon melanotheron from southwestern nigeria. | dna barcoding has been adopted as a gold standard rapid, precise and unifying identification system for animal species and provides a database of genetic sequences that can be used as a tool for universal species identification. in this study, we employed mitochondrial genes 16s rrna (16s) and cytochrome oxidase subunit i (coi) for the identification of some nigerian freshwater catfish and tilapia species. approximately 655 bp were amplified from the 5' region of the mitochondrial cytochrome c o ... | 2016 | 27990256 |
