Question

A population of dragonflies includes both clear-winged and yellow-winged individuals. Those with clear wings live longer and reproduce many more times than those with yellow wings.
An image of Clear-winged dragonflies.
Based on this information, what change is most likely to happen in this population over time?

A.
Dragonflies with clear wings will disappear completely from the population.
B.
Individual dragonflies that have both clear and yellow wings will appear in the population.
C.
The population will have fewer dragonflies with yellow wings.
D.
The population will have fewer dragonflies with clear wings.

Answer 1

Based on the information provided—where clear-winged dragonflies have a longer lifespan and reproduce more often than yellow-winged individuals—the most likely change in the population over time is:

C. The population will have fewer dragonflies with yellow wings.

This conclusion is drawn from the principle of natural selection, where individuals with advantageous traits (in this case, clear wings) are likely to survive longer and reproduce more, leading to a decrease in the proportion of individuals with less advantageous traits (yellow wings).
