Genetypes is a taxonomic concept proposed in 2010 to describe any genetic sequences from type specimens. This nomenclature integrates molecular systematics and terms used in biological taxonomy. This nomenclature is designed to label, or flag, genetic sequences that were sampled from type specimens. The nomenclature of genetypes proposes that genetic sequences from a holotype should be referred to as a “hologenetype” (from: holotype and genetype), sequences from a topotype will be a “topogenetype,” and so forth. In addition, the genetic marker(s) used should also be incorporated into the nomenclature (e.g., paragenetype ND2).
