Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Gene flow refers to the movement of alleles from one population to another as a result of interbreeding between members of two populations. The random introduction of new alleles into the recipient population and their removal from the donor population affects the allele frequency of both population and leads to increased genetic variation. Gene flow must be interrupted for the origin of new species.
So, the correct option is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'.
