Genus vs. Species

The main difference between Genus and Species is that Genus is a rank in the classification of the organism, below Family and above Species, and Species is the taxonomic unit, ranking below a Genus. A species is a group of populations in which genes are exchanged through the way of interbreeding or matting.

Key Differences

In binomial nomenclature, the first part of the name is known as genus and second part of the name is called species.
The genus contains a large number of organisms while species contains less amount of microorganisms.
Genus ranks below family, but species is the final level of binomial nomenclature.
Different subspecies make the species and different species make the genus.

Genus and Species Definitions

Genus

(Biology) A taxonomic category ranking below a family and above a species and designating a group of species that are presumed to be closely related and usually exhibit similar characteristics. In a scientific name, the genus name is capitalized and italicized, for example, Ovis for sheep and related animals.

Species

(Biology) A group of closely related organisms that are very similar to each other and are usually capable of interbreeding and producing fertile offspring. The species is the fundamental category of taxonomic classification, ranking below a genus or subgenus. Species names are represented in binomial nomenclature by an uncapitalized Latin adjective or noun following a capitalized genus name, as in Ananas comosus, the pineapple, and Equus caballus, the horse.

Genus

(Logic) A class of objects divided into subordinate species having certain common attributes.

Species

(Logic) A class of individuals or objects grouped by virtue of their common attributes and assigned a common name; a division subordinate to a genus.

Genus

A class, group, or kind with common attributes.

Species

(Chemistry) A set of atoms, molecules, ions, or other chemical entities that possess the same distinct characteristics with respect to a chemical process or measurement.

Genus

A category in the classification of organisms, ranking below family (Lat. familia) and above species.
All magnolias belong to the genus Magnolia.
Other species of the genus Bos are often called cattle or wild cattle.
There are only two genera and species of seadragons.

Species

A category in the classification of organisms, ranking below genus; a taxon at that rank.

Genus

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.

Species

A particular type of atom, molecule, ion or other particle.

Genus

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 genus is not necessarily the lowest definable group of species, for it may often be divided into several subgenera. In proportion as its definition is exact, it is natural genus; if its definition can not be made clear, it is more or less an artificial genus.

Genus vs. Species

Genus and Species are both the taxonomic ranks in the biological classification of an organism. The organism from a separate Genus cannot produce offspring that are capable of reproduction. Species is the largest group of organisms whose subspecies can breed and reproduce offspring which are able to reproduce as well. Genus comes just above the species in an organism’s taxonomic hierarchy whereas a species is the lowest and final level of the classification. Genus is composed of any number of species, but a Species is comprised of any number of subspecies having similar features. In the scientific classification of any organism first part of the name is called generic name while the second part of the name is known as a species name. The genus contains a large number of the organism while species contains less number of the organism. Genus is composed of different species while species is composed of different subspecies.

What is a Genus?

Genus is a rank in the taxonomic hierarchy that includes a large number of closely related species. Genus is a singular noun, and in plural form, it is “genera.” Organisms from separate genera cannot produce offspring that is capable of reproduction. A genus comprised of more than one species and these species have similar characteristics. The genus name of a specific individual is written in italics and is the first word of the scientific name of an organism. The first letter of the genus name is always capitalized.

Example

The scientific name of humans is Homo sapiens, in which the genus name is Homo as the first segment of the binomial name of any particular organism is its generic name. Like as an abbreviation, it is common practice to capitalize the first letter of the genus name like (for example in case of (H. Sapiens). Genus names are sometimes given an English flavor to make it sound more usual. A genus name is also called as the generic epithet or generic name.

What is Species?

Species are the most basic and lowest level in a taxonomic hierarchy in which the group of organisms having similar features or attributes and capable of producing fertile offsprings. Individuals of the same species have identical chromosome counts; it means that they have an identical structure and form. Organisms in a species usually share the same features intrinsic only to their species. In taxonomy, any number of species may comprise a single genus, which makes it the ancestor of the species. The name of the species is the second part of an organism’s scientific name. It is generally written in italics and lowercase letters.

Example

For example, in the case of the scientific name of humans, that is Homo sapiens. The second part of the scientific name of humans is its species name.
