Genus

In biological classification, a genus is a rank used in the biological classification of living and fossil organisms, as well as viruses, in biology. In the hierarchy of biological classification, genus comes above species and below family.

Characteristics of a Genus

• Grouping: A genus includes one or more species that are closely related and share common characteristics.
• Binomial nomenclature: Each genus is given a unique scientific name using binomial nomenclature, which consists of the genus name followed by the species name. For example, the genus Rosa includes species such as Rosa canina (dog rose) and Rosa chinensis (China rose).
• Taxonomic rank: Genus is a taxonomic rank used in the biological classification of organisms.
