The term genus was borrowed from Latin.
A genus represent one of several hierarchical categories called taxa (singular taxongenera (plural of genus) include only a small group of species which evolved from a relatively recent common ancestor. They have relatively smaller teeth than other primates. ə r.ə / us / ˈdʒen. The names of genera, like those of species, are written in italics. A genus has no natural, much less necessary, definition, its meaning being at best a matter of expert opinion; and the same is true of the species, family, order, class, etc. For example, … ə r.ə / a group of animals or plants, more closely related than a family, but less similar than a species Thesaurus: synonyms and related words Dogs and wolves are so closely related they’re in the same genus.
This is a term used by biologists to classify more than one species under a larger umbrella. A sphere has genus 0, a torus, genus 1, etcA taxonomic category ranking below a family and above a species and generally consisting of a group of species exhibiting similar characteristics.A group of organisms ranking above a species and below a family. Genus Definition. In this form it is never pluralized. Copyright © 2011. It denotes the number of beings, or objects, which agree in certain general properties, common to them all, so that genus is, in fact, only an abstract idea, expressed by some general name or term; or rather a name or term, to signify what is called au abstract idea.
