GENUS

n. category in which living organisms with common characteristics are classified (Biology); category, class, kind

A genus (plural: genera) is part of the Latinized name for an organism. It is a name which reflects the classification of the organism by grouping it with other closely similar organisms. A genus is a category name that is given to every species in a group of species which are closely related to one another. Ideally the same generic name is given to species which are all descended from a common ancestor. In other words, a genus is a low-level taxonomic unit, used in the classification of living and fossil organisms.
