Question

Assertion (A): Gene flow increases genetic variations.

Reason (R): The random introduction of new alleles into a recipient population and their removal from donor population affects allele frequency.

विकल्प

• Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).

• Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).

• Assertion (A) is true, but Reason (R) is false.

• Assertion (A) is false, but Reason (R) is true.

Answer 1

Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).

Explanation:

The process by which migrant individuals reproduce within the new population is known as gene flow or gene migration. The host population's local gene pool will gain additional alleles from the newcomers. Through breeding, the genes of two populations combine, producing differences in the progeny. Allelic frequencies in both populations are impacted by the random entrance of alleles into the recipient population and their removal from the donor population.
