Question

The third name in the trinomial nomenclature is?

• A. Species
• B. Subgenus
• C. Subspecies
• D. Ecotype

Answer 1

The correct option is C Subspecies

Trinomial nomenclature is employed to name the subspecies. In classification, the subspecies is a category below the species. The sub specific name is also a Latin or Latinised word and follows the name of the species to which it belongs. For example, the specific name of the house crow, which occurs throughout India, Pakistan, Burma and Sri Lanka it Corvus splendens. The house crows of India and Pakistan, Burma and Sri Lanka differ with each other in minute morphological features and are thus, separated as distinct subspecies. The Indian and Pakistani house crow has been assigned the subspecific name Corvus splendens splendens, the Burmese house crow is Corvus splenders insolens and the Sri Lankan house crow is Corvus splendens protegatus. Mostly in botanical literature, the third name represents variety whereas in zoological literature, the third name represents subspecies.

So the correct option is option C.
