Genus (/ ˈ dʒ iː n ə s /; pl.: genera / ˈ dʒ ɛ n ər ə /) is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses. [1] In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.
However, to avoid repetition of taxonomic names which break the flow of prose, vernacular names of members of a genus or higher taxa are often used and recommended, these are formed by writing the name of the taxa in sentence case roman ("standard" in MS Office) type, therefore treating the proper noun as an English common noun (e.g. the ...
The genitive -é suffix is only used with the predicate of a sentence: it serves the role of mine, yours, hers, etc. The possessed object is left in the nominative case. For example: A csőr a madáré ('The beak is the bird's'). If the possessor is not the predicate of the sentence, the genitive is not used.
A taxon is usually assigned a rank when it is given its formal name. The basic ranks are species and genus. When an organism is given a species name it is assigned to a genus, and the genus name is part of the species name. The species name is also called a binomial, that is, a two-term name.
The hierarchy of scientific classification. Taxonomy mnemonics are used to memorize the scientific classification applied in taxonomy. They are usually constructed with a series of words that begin with the letters KPCOFGS, corresponding to the initials of the primary taxonomic ranks.
The principal ranks in modern use are domain, kingdom, phylum (division is sometimes used in botany in place of phylum), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms ...
A genus–differentia definition is a type of intensional definition, and it is composed of two parts: . a genus (or family): An existing definition that serves as a portion of the new definition; all definitions with the same genus are considered members of that genus.
An interpolated name is italicized and placed in non-italic parentheses (round brackets); some examples are after a genus name to indicate a subgenus, after a genus group to denote an aggregate of species, after a species name to mean an aggregate of subspecies, after a genus and the word "section" or "sect." to provide a botanical genus ...
