Question

Assertion: Gene flow increase genetic variations.
Reason: The random introduction of new alleles into recipient population and their removal from the donor population affects allele frequency.

• A. If both Assertion and Reason are true and Reason is the correct explanation of the Assertion.
• B. If both Assertion and Reason are true but the Reason is not the correct explanations of Assertion.
• C. If Assertion is true, but Reason is false.
• D. If both Assertion and Reason are false.

Answer 1

Answer: (B)

Gene flow is the movement of alleles from one population to another as a result of interbreeding between members of the 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 populations and leads to increase genetic variation.
