genus
A scientific group that includes one or more closely related species; it is above species and below family.
A principal rank in biological classification that groups closely related species and is ranked above species and below family.
A very general group or class that can be divided into smaller kinds.
A broad class or category under which more specific types (species) are grouped, especially in logic and philosophy.
In math, a number that shows how many holes a surface has.
In mathematics, especially topology, a number that represents how many handles or 'holes' a surface has (e.g., sphere: 0, torus: 1).
- Base: genus
- Plural: genera, genuses
at the genus level
1At the genus rank
Talking about classification using the genus, not species or family.
- The analysis was done at the genus level due to limited data.
- Some traits are only informative at the genus level.
genus and species
1Binomial name pair
The two parts of a scientific name: the genus and the species.
- In biology class we learned to write the genus and species for each organism.
- The label shows the genus and species of the plant.
genus name
1First part of a binomial name
The first word in a scientific name, which shows the genus.
- The genus name is capitalized and italicized.
- In Homo sapiens, Homo is the genus name.
of the genus
1Belonging to a genus
Used to say that something is in a certain genus.
- We collected several orchids of the genus Dendrobium.
- This fossil is of the genus Australopithecus.
surface of genus g
1Topology: surface with g holes
A math way to describe a surface by saying how many holes it has.
- The algorithm works for any surface of genus g.
- They studied embeddings on a surface of genus two.
within the genus
1Inside a particular genus
Used to talk about members or differences inside one genus.
- Variation within the genus is surprisingly high.
- Within the genus Canis, dogs and wolves can interbreed.
