For eg., lion and tiger are placed under the genus Panthera. The names of genera and species are usually printed in italics. Genus belongs to a ranking lower than family and above species, whereas species are organisms with similar characteristics that come below the Genus classification ranking. The type (i.e., holotype) is the specimen that has been designated in the taxonomic literature as typical of a species. post. A genus is a low-level taxonomic rank used in the classification of living and fossil organisms, and also any taxonomic unit (taxon) of that rank. A genus is a class or group of something.

In contrast, the division of genus is more specific as the grouping before species and after family. The main difference between species and genus is the taxonomic rankings that are used for biological classifications of organisms. There are about 8.7 million different species on earth. A group of similar species forms a genus. The common dog, Canis lupus familiaris, is a subspecies of Canis lupus, which also includes the wolf and dingo. The word "type" has special meaning in biology. Biology Stack Exchange is a question and answer site for biology researchers, academics, and students. 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.
