Scientific binomial name consists of two parts.

• A. Genus followed by the specific epithet
• B. Family and genus
• C. Species and cultivar
• D. Genus and species

Answer: (A)

Two-part scientific names use a genus and a specific epithet. The genus groups closely related organisms, and the specific epithet distinguishes the species within that genus. Together they uniquely name the species. For example, Homo sapiens: Homo is the genus, sapiens is the specific epithet. In plants, Rosa canina follows the same pattern. The convention is to capitalize the genus and use a lowercase epithet, with both usually written in italics. A family plus genus wouldn’t identify a single species, a genus plus a cultivar names a cultivated variety, and a genus plus “species” uses the wrong second term for the binomial.
