Question

Populations are said to be sympatric when

• A. Two populations live together and freely interbreed to produce sterile offspring.
• B. Two populations are physically isolated by natural barriers.
• C. Two populations are isolated but ocassionally come together to interbreed.
• D. Two populations share the same environment but cannot interbreed.

Answer 1

The correct option is D Two populations share the same environment but cannot interbreed.

In sympatric speciation, groups from the same ancestral population evolve into separate species without any geographical separation. In this case, divergence is facilitated by the absence of gene flow.

So, the correct answer is " Two populations share the same environment but cannot breed".
