In biology, a genus (plural: genera) is a taxonomic unit (a taxon) used in the classification of living and fossil organisms. The term comes from Latin genus "descent, family, type, gender" (plurals: genera), cognate with Greek: γένος – genos, "race, stock, kin" (plurals: genera)..
In addition, genus (not countable, no plural) is a taxonomic rank in the hierarchy (thus "a genus" is a taxon at the rank of genus). Other well-known taxonomic ranks a...

In biology, a genus (plural: genera) is a taxonomic unit (a taxon) used in the classification of living and fossil organisms. The term comes from Latin genus "descent, family, type, gender" (plurals: genera), cognate with Greek: γένος – genos, "race, stock, kin" (plurals: genera)..
In addition, genus (not countable, no plural) is a taxonomic rank in the hierarchy (thus "a genus" is a taxon at the rank of genus). Other well-known taxonomic ranks are: kingdom, phylum, class, order, family, and species, with genus fitting between family and species. Like for the other well-known taxonomic ranks, mentioned above, there can be an immediately lower rank, indicated by the prefix sub-, in this case subgenus (plural subgenera). The most important taxonomic unit below the genus is the species, which is the basic rank.
The composition of each genus is determined by a taxonomist, but often there is no exact agreement, with different taxonomists each taking a different position. There are no hard...
