Monotypic genera is ?

Definition
A monotypic genus is a genus that contains only one species. It is a term used in biological classification to describe a genus that consists of a single species.

Examples of Monotypic Genera
Some examples of monotypic genera include:

- Homo: This genus consists of only one living species, Homo sapiens, which is the modern human being.

- Pan: This genus consists of two species, the common chimpanzee (Pan troglodytes) and the bonobo (Pan paniscus). However, some taxonomists consider the bonobo to be a subspecies of the common chimpanzee, making the genus Pan monotypic.

- Solanum: This genus is the largest in the family Solanaceae and includes over 1,500 species. However, the potato (Solanum tuberosum) is the only one that is cultivated for human consumption, making the genus Solanum monotypic in practical terms.

Significance
Monotypic genera are significant in biological classification because they represent a unique evolutionary lineage. They may also be of interest to biologists studying a particular species or group of organisms, as they provide a clear focus for research.

Conclusion
In conclusion, a monotypic genus is a genus that contains only one species, and examples include Homo, Pan, and Solanum. While they may not be as common as genera with multiple species, monotypic genera are significant in biological classification and may be of interest to researchers studying a particular species or group of organisms.

Monotypic genera means genus consists of only one species.
So answer is option 3. Under genus Homo only one species is there i.e, sapiens.

Polytypic genera means genus consists of more than one species Under genus Panthera the different specific epithets are leo,tigris,pardus.Under genus solanum the different specific epithets are tuberosum,nigrum etc.
