Question

Physically separated groups lead to

• A. Geographical isolation
• B. Mechanical isolation
• C. Temporal isolation
• D. Hybrid sterility
• E. Behavioral solution

Answer 1

The correct option is A Geographical isolation

The presence of populations of a species in distant localities preventing the gene flow between them leads to geographical isolation. Incompatible differences in reproductive structures refer to as mechanical isolation. Different periods of attainment of sexual maturity lead to temporal isolation. Hybrid sterility is a post zygotic isolation. Incompatible premating behaviour leading to no attraction between groups for mating is termed as behavioural isolation. Thus, the correct answer is A.
