Question

Related species, which are reproductively isolated but morphologically similar are called as

• A. Sibling
• B. Sympatric
• C. Allopatric
• D. Morphospecies

Answer 1

The correct option is A Sibling

Sibling species are morphologically indistinguishable, but are reproductively isolated.

Sympatric species occurs when there are no physical barriers preventing any members of a species from mating with another and all members are in close proximity to one another.

Allopatric species occurs when a species separates into two separate groups which are isolated from one another. A physical barrier, such as a mountain range or a waterway, makes it impossible for them to breed with one another.

Morphospecies is a group of biological organisms that differs in some morphological respect from all other groups.
