Question

Which of the following species is restricted to an area? (a) Sibling species (b) Endemic Species (c) Allotropic Species (d) Sympatric Species.

Answer 1

Sibling species:
Species that are morphologically nearly identical and closely related genetically, but which are reproductively isolated and cannot interbreed successfully to produce fertile offspring.
Endemic species:
Endemic species are plants and animals that exist only in one geographic region.
Allopatric species:
It is a mode of speciation that occurs when biological populations of the same species become isolated from each other to an extent that prevents or interferes with genetic interchange.
Sympatric species:
Sympatric speciation is the process through which new species evolve from a single ancestral species while inhabiting the same geographic region.

Therefore the correct answer is
Option B that is Endemic species.

I hope this would have been clear to you.
