Question

Trinomial nomenclature of classification was proposed by
A. Linnaeus
B. Huxley and Strickland
C. John Ray
D. Theophrastus

Answer 1

Hint: Nomenclature refers to the scientific naming of organisms. Every organism is given a two-word name that consists of a genus name as the first word and a species name as the second. The trinomial nomenclature consists of a three-word naming system.

Complete answer: Nomenclature refers to the naming of organisms based on scientific terms. Every organism is known by its local name in its native region but with a change in location, the name changes. This makes identification difficult for scientific studies. Therefore, to eliminate this confusion, Linnaeus gave an idea of the scientific names for each organism. The first nomenclature is the binomial nomenclature. Every taxonomical technique follows some rules. Thus, nomenclature also has certain rules. Like binomial nomenclature, the trinomial nomenclature includes species and genera names. The difference in binomial and trinomial nomenclature is that an additional subspecies name is included in trinomial nomenclature after the species name. The binomial nomenclature was given by Linnaeus. He is considered the father of taxonomy. On the other hand, the idea of trinomial nomenclature was proposed by Huxley and Strickland. They named an organism based on three words. The third word specifies the intraspecific or subspecific epithets. Both the binomial and trinomial nomenclature follows almost the same set of rules. For example in Brassica oleracea capitata, the word ‘Brassica’ is thegenera name, ‘oleracea’ is the species name and ‘capitata’is the variety name. In plants, after the subspecies names, the other names like for variety and form and many other ranks can be provided. Another example of trinomial nomenclature is of a red-tailed hawk subspecies. It is called Buteo jamaicensis borealis. The term ‘borealis’ is the subspecies term.
Therefore, the right answer is option B.

Note: Zoology and botany follow different rules for naming animals and plants respectively based on trinomial nomenclature. In the case of zoology, only one more name can be added after the genera and species name. But in botany, an indeterminate number of intraspecific or subspecific names are allowed after the level of species.
