Question

② Biological concept of species​

Answer 1

The Biological Species Concept defines a species taxon as a group of organisms that can successfully interbreed and produce fertile offspring. According to that concept, a species' integrity is maintained by interbreeding within a species as well as by reproductive barriers between organisms in different species...

Answer 2

Answer :-

The various concepts of species are as follows :-

• Species is the basic unit of taxonomy.

• Species inhibiting the same geographical area (identical or overlapping), are termed as "Sympatric" species.

• Related species which are reproductively isolated but morphologically similar, are known as "Sibling" species.

• A species restricted to a particular area, is known as "Endemic" species.

• Species that contain two or more sub-species, are known as "Polytypic" species.

• Species that are not divided into sub-species, are known as "Monotypic" species.

• In general cases, breeding is possible only within the organisms belonging to the same species.

• Accumulation genotypic changes in a population leads to the formation of a new species which ultimately leads to reproductive isolation.

Note :-

The concepts of species were given by "Ernst Mayr".
