Question

a group of students is walking in the park, and one of them takes a picture of a pollen grain that is being blown by the wind. what caption can the student use for this picture?
○ gene mutation in action
○ gene flow at work
○ genetic drift as it happens
○ natural selection in progress

Explanation:

To determine the correct caption, we analyze each option:

• "Gene mutation in action" involves changes in DNA, not pollen movement.
• "Gene flow at work" occurs when genes are transferred between populations (e.g., pollen carrying genetic material between plants via wind).
• "Genetic drift as it happens" refers to random changes in gene frequencies (e.g., small population events), not pollen movement.
• "Natural selection in progress" involves differential survival/reproduction, not pollen transport.

Pollen movement via wind transfers genetic material, so it represents gene flow.

Answer:

B. gene flow at work
