In the binomial name, which term represents the genus?

• A. Genus
• B. Species
• C. Family
• D. Order

Answer: (A)

The main idea is how binomial names are structured. In binomial nomenclature, the first word is the genus—the group that includes closely related species. It is capitalized and sets the broader category for the organism. The second word is the species epithet, which identifies the exact species within that genus. For example, in Solanum lycopersicum, Solanum is the genus, grouping related plants like potatoes and eggplants, while lycopersicum specifies the tomato species. Higher ranks like family and order exist in the broader classification system, but they are not part of the two-part name. So the genus is the first term.
