Understanding Genus and Taxonomic Classification — NEET Biology
📚 Practice ConceptGenus comprises a group of related species which has more characters in common in comparison to species of other genera. We can say that genera are aggregates of closely related species. For example, potato and brinjal are two different species but both belong to the genus Solanum. Lion (Panthera leo), leopard (P. pardus) and tiger (P. tigris) with several common features, are all species of the genus Panthera. This genus differs from another genus Felis which includes cats.
Match the following taxonomic categories with their defining features and a relevant example: Column I (Taxonomic Category) A. Genus B. Family C. Order D. Class Column II (Defining Feature) i. Aggregates of closely related species ii. Group of related genera with fewer similarities than genus/species iii. Assemblage of families based on aggregate characters iv. Category that includes related orders Column III (Example of Member/Group) 1. *Solanum* 2. Felidae 3. Primata 4. Mammalia Which of the following options represents the correct match?
View solution & NCERT explanation
Correct answer: A — A-i-1, B-ii-2, C-iii-3, D-iv-4
This question requires matching taxonomic categories with their definitions and specific examples as provided in the NCERT text. A. Genus: According to NCERT, "genera are aggregates of closely related species." (*Solanum* is given as an example of a genus, e.g., *Solanum tuberosum*, *Solanum nigrum*, *Solanum melongena*). Thus, A-i-1 is the correct match. B. Family: NCERT defines Family as "a group of related genera with still less number of similarities as compared to genus and species." Felidae is presented as an example of a family including genera like *Panthera* and *Felis*. Thus, B-ii-2 is the correct match. C. Order: NCERT states that an Order is an "assemblage of families which exhibit a few similar characters." Primata is given as an example of an order. Thus, C-iii-3 is the correct match. D. Class: NCERT mentions that Class "includes related orders." Mammalia is an example of a class that includes orders like Primata and Carnivora. Thus, D-iv-4 is the correct match. Combining these matches, the correct option is A. A-i-1, B-ii-2, C-iii-3, D-iv-4.
