After an earthquake, a certain species of frog was split into two populations by a fault and the populations on either side of the fault began to diverge. After a period of time, some members of the two populations began to interbreed in a hybrid zone at one edge of the fault. Only weak reproductive barriers existed by this time, so the two populations could freely interbreed and re-establish gene flow. This outcome in a hybrid zone is known as _____.
