Question

Which of the following species are restricted to a given area?

• A. Sympatric species
• B. Allopatric species
• C. Sibling species
• D. Endemic species

Answer 1

The correct option is D Endemic species

Endemic species are restricted to a given area for various reasons like some special requirements for optimum growth, soil and other environmental conditions etc. Biodiversity hotspots are the regions with very high levels of species richness and a high degree of endemism.

Sympatric species are the species formed from a single ancestor due to reproductive isolation but inhabit the same geographic location.

Allopatric species are those which are formed as a result of physical barrier.

Sibling species are morphologically identical species which can produce fertile offsprings.

Thus, the correct answer is option D.
