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:

• Gene mutation: Involves changes in DNA sequence, not related to pollen movement by wind.
• Gene flow: Occurs when genes are transferred between populations, like pollen (carrying genetic material) being moved by wind to new areas, which matches the scenario.
• Genetic drift: Random change in gene frequencies in small populations, not about pollen dispersal by wind.
• Natural selection: Process where organisms with favorable traits survive, not related to pollen movement.

Answer:

B. gene flow at work
