Question

if a population has high genetic variation, what is the most likely outcome if its environment changes suddenly?
the population is more likely to survive the environmental change.
the population will become less adapted to the environment.
all individuals in the population will remain exactly the same.
the population will stop having any genetic differences.

Explanation:

The question is about population and environmental change, related to genetic variation's role in survival. The first option states a population with more genetic variation is more likely to survive environmental change, which aligns with evolutionary biology concepts (more variation means more chance of beneficial traits for new environment). The second option is incorrect (variation helps adaptation, not reducing it). The third is wrong (genetic variation exists, individuals aren't identical). The fourth is incorrect (genetic differences are key for evolution, not stopping). So the first option is correct.

The top - most blue box option: "The population is more likely to survive the environmental change."
