Question

In which of the following mechanism, there is no interaction between the groups for mating?

• A. Geographical isolation
• B. Mechanical isolation
• C. Temporal isolation
• D. Reproductive isolation
• E. Behavioral isolation

Answer 1

The correct option is E Behavioral isolation

Physical separation of groups 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 one of the post-zygotic isolation. Incompatible premating behaviour leading to no attraction between groups for mating is termed as behavioural isolation. Thus, the correct answer is E.
