subspecies
Quick Summary
A taxon is any unit used in biological classification, or taxonomy. Taxa are organized hierarchically, from kingdom down to subspecies. A subspecies is a subdivision of a species, typically a population from a specific geographic area that is genetically distinct but can still interbreed with other populations of the same species where their ranges overlap. In zoology, distinct populations of a widespread species that have developed local variations are often classified as subspecies, indicated by a trinomial name (e.g., Pachycephala pectoralis bougainvillei). In botany, terms like "variety" and "form" are often used for variants below the subspecies level.123
