How do you deal with this?

CO1 meaning Cytochrome oxidase subunit one or COI which is cytochrome oxidase sub unit I (as in letter I)? What's the proper way? Both? Let us say I am lecturing in an international convention. scientifically-wise, which is right?112.207.137.124 (talk) 11:45, 14 April 2015 (UTC)[reply]

Both are correct in that in the form "COI", the letter I is used as a roman numeral (subunit I, subunit II) so should still be pronounced "subunit one", although the mixture of "English" capitals and "latin" numerals is non-obvious (and unfortunate). The literature seems evenly divided between "CO1" and COI" at this time. I do not attend barcoding conventions but would be interested to hear whether speakers pronounce the two variant spellings the same or not... Tony 1212 (talk) 00:31, 6 August 2018 (UTC)[reply]
