Question

Species having many subspecies are
A. Monotypic/Microspecies
B. Allopatric
C. Sibling
D. Polytypic/Macrospecies

Answer 1

Hint: Species is defined as the group of organisms which have common characters and they can interbreed and can produce fertile offsprings.

Complete Answer:
- Monotypic/Microspecies: Microspecies are those species which differ only in minor characteristics from others of its group. These species contain only one type of subspecies. These are the species in which variations are very less. The members of these species reproduce asexually so that they have less variation.

- Allopatric species: Allopatric species are those species that do not have overlapping geographic ranges. These species are physically isolated from other similar groups by an extrinsic barrier. The members of these species can not interbreed.

- Sibling species: Sibling species are those species which look alike. But the members of these species cannot breed with each other. The members of these species are almost identical. Example – Drosophila pseudoobscura and Drosophila persimilis.

- Polytypic/macrospecies: Polytypic species are those species that contain more than one subspecies. In these species variations are more than that of microspecies. They reproduce by sexual mode which involves the fusion of gametes from two different parents.

Hence, option D is the correct option for this question.

Note: These different kinds of species formed by the process called Speciation. Speciation is the process of formation of new genetically independent groups of organisms that are called species. The formation of new species takes through the process of evolution. There are two ways for speciation to occur.
