{i} category in which living organisms with common characteristics are classified (Biology); category, class, kind
"Genus" is the next to the lowest level of plant classification The lowest level is "species" All known living organisms are organized into a classification system This is part of the science called "taxonomy" Scientists refer to living things by a combined "genus" and "species" name, using Latin terms For example, people are called "Homo sapiens" A white pine would be called "Pinus strobus" A scientist anywhere in the world can look up information about any living organism by knowing the Latin or scientific name The genus name is always capitalized The species name is usually not capitalized The plural form of "genus" is "genera" [To return to previous page, click your browser's BACK button then scroll through the page to your last location]
Roughly speaking, this is the number of holes through a polyhedron (or other 3D object) A cube has genus 0, a doughnut has genus 1, and so on With many self-intersecting polyhedra, including many uniform polyhedra, it can be hard to say what the genus is just by looking at them, since the "holes" may not be apparent due to intersecting faces getting in the way
(biology) taxonomic group containing one or more species
A genus is a class of similar things, especially a group of animals or plants that includes several closely related species. genera one of the groups into which scientists divide animals or plants, in which the animals or plants are closely related but cannot produce babies together. A genus includes fewer members than a family and more members than a species. Biological classification. It ranks below family and above species, consisting of structurally or phylogenetically (see phylogenetic tree) related species or a single species exhibiting unusual differences. For example, the species of roses collectively form the genus Rosa and those of horses, donkeys, and zebras form the genus Equus. The genus name, capitalized and usually italicized, is the first word of a scientific name in the system of binomial nomenclature
A class of objects divided into several subordinate species; a class more extensive than a species; a precisely defined and exactly divided class; one of the five predicable conceptions, or sorts of terms
in biology, a category that's part of the scientific system for grouping together related plants, animals and other organisms (kingdom, phylum, class, order, family, genus, species) Genus is the category that ranks below a family and above a species
taxonomic division of related species below family

A genus is not necessarily the lowest definable group of species, for it may often be divided into several subgenera
The term for a group of closely related species (pl genera)

An assemblage of species, having so many fundamental points of structure in common, that in the judgment of competent scientists, they may receive a common substantive name
A numerical integer invariant of an algebraic curve As applied to a topological object such as 2-dimensional manifold, it can be interpreted as the number of "handles" the object has E g a sphere has genus 0, while a torus (donut shape) has genus 1 There are various other definitions, such as the dimension of the space of differential (1-)forms

1 In geometric topology, the number of holes of a surface Usually this means the maximum number of disjoint circles that can be drawn on the surface such that the complement is connected If there are no such circles, the surface is planar, and the genus then sometimes means the maximum number of disjoint arcs with the same property 2 A measure of the twistedness of a fiber bundle Technically, if X is a topological space with a fiber bundle F, it is the minimum number of open sets that cover X such that F is trivial over each open set 3 Some other number which generalizes or is analogous to the topological genus, such as the arithmetic genus of an algebraic curve
a grouping of similar species according to taxonomic criteria, for example, humans (Homo sapiens) belong to the genus 'Homo' and the species 'sapiens'
