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.
Study Guide for Genus
When studying the concept of genus, it is important to understand the following key points:
- Define genus and its position in the hierarchy of biological classification.
- Understand the concept of binomial nomenclature and how genus and species names are used to scientifically classify organisms.
- Learn to differentiate between different genera and recognize the unique characteristics that define each genus.
- Explore examples of different genera and the species they encompass.
- Practice classifying organisms into their respective genera based on their shared characteristics.

The Living Environment: Students understand that cells are the basic unit of life, that all life as we know it has evolved through genetic transfer and natural selection to create a great diversity of organisms, and that these organisms create interdependent webs through which matter and energy flow. Students understand similarities and differences between humans and other organisms and the interconnections of these interdependent webs.
Biodiversity: Students compare living things based on their behaviors, external features, and environmental needs.
Describe how living things can be sorted in many ways, depending on which features or behaviors are used to sort them, and apply this understanding to sort living things.
