Explanation: did the test and got it right
ANSWER:
Dark coloured fish living in lake B while bright colored fish living in lake A, each group of fush have same gene fool where random mating is possible and chances of speciation is null. However, when migration of one group of fish occur toward another group of fish then gene flow also occured. This result into breeding amongst members of two different groups. So the chances for speciation increase, and it is possible that with the passage of time new species may develop.
