WGenus

In biology, a genus /ˈdʒiːnəs/ (plural: genera) is a taxonomic rank used in the biological classification of living and fossil organisms. In the hierarchy of biological classification, genus comes above species and below family.
E.G., Pongo pygmaeus and Pongo abelii are two species within the genus Pongo. Pongo is a genus within the family Hominidae.
The composition of a genus is determined by a taxonomist. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera.
