If two populations that are geographically distant from one another regularly experience gene flow (ex: through migration), those populations are most likely Blank______.Multiple choice question.the same speciestwo different speciesthe same subspecies, but not the same species
Solution
The correct answer is "the same species". Gene flow is the transfer of genetic variation from one population to another. If two populations are experiencing regular gene flow, it means individuals are migrating and breeding between the populations, which is a characteristic of them being the same species. Different species cannot interbreed and produce fertile offspring, so they would not experience gene flow. Subspecies are not distinct enough to be considered separate species, but they are usually geographically isolated and do not regularly interbreed.
