The correct answer is: A.Crossbreeding with individuals from different populations.

Explanation:

When individuals from different populations crossbreed, they introduce new alleles into the gene pool, increasing genetic diversity. This process, known as gene flow, introduces genetic variation that might not have been present in the original population.

Here's why the other options are less likely to increase genetic diversity:

B.Reducing migration between populations: Limiting migration reduces gene flow between populations, which would decrease genetic diversity. Without the exchange of al...
