False. That is species.
Organisms in each level of classification contains organisms with similarities, but species is the most specific (hence the two words, "species" and "specific" sounding very alike).
Though genus does include very similar organisms, species include the exact one.
Here are the different levels of classification (going from the most general to the most specific)
- domain
- kingdom
- phylum
- class
- order
- family
- genus
- species
