Question

which of the following is the correct definition of gene flow? select an answer a. individuals with intermediate phenotypes surviving and reproducing more successfully than others within the population b. a process in which bacteria can pass genes directly to another bacterium c. random changes in allele frequency in a small population d. the exchange of alleles between populations

Explanation:

• Option A describes stabilizing selection.
• Option B is bacterial conjugation (a type of horizontal gene transfer, not gene flow).
• Option C is genetic drift.
• Option D matches the definition of gene flow (exchange of alleles between populations).

Answer:

D. the exchange of alleles between populations
