Solution
The correct answer is: "will experience gene flow, but will remain two distinct species".
Here's why:
Gene flow is the transfer of genetic variation from one population to another. If two populations come into physical contact with each other, they will likely experience gene flow. However, this does not necessarily mean they will become one species.
For two populations to merge into one species, they would need to be completely reproductively isolated for a long period of time. This means that individuals from the two populations cannot interbreed to produce viable, fertile offspring.
In this scenario, the two populations have not evolved independently for a long enough time to be completely reproductively isolated. Therefore, while they may exchange genetic material, they will remain two distinct species.
