Which term in a binomial name may be abbreviated with a single letter?Multiple choice question.The genusThe specific epithet

The correct choice is: The genus.

In biological nomenclature, specifically in the binomial naming system established by Carl Linnaeus, the name of a species is composed of two parts: the first part is the genus name and the second part is the specific epithet. The genus name can be abbreviated to a single letter when referencing multiple species within a similar genus, such as "A. thaliana" for Arabidopsis thaliana. However, the specific epithet is not typically abbreviated. Thus, the genus is the term that may be abbreviated with a single letter.
