Genera in Biology

In biology, a genus (plural: genera) is a taxonomic rank used in the classification of living organisms. It is one of the levels in the hierarchical classification system, which goes from the most general to the most specific: domain, kingdom, phylum, class, order, family, genus, and species.

Characteristics of Genera

Each genus groups together species that are closely related and share a common ancestor. Organisms within the same genus have more similarities in terms of their physical characteristics, genetics, and evolutionary history compared to organisms in different genera.

Naming Conventions

Genera are given Latin names and are always italicized or underlined when written. The genus name is always capitalized. For example, in the scientific name "Canis lupus," Canis is the genus name for wolves.
