Imagine You Are Standing in a Field and You See

Imagine you are standing in a field and you see a group of butterflies. You notice an individual that looks significantly different from the other butterflies in the populations: It has much larger wings and can fly faster than the other butterflies. This difference allows the butterfly to escape predation more efficiently than other butterflies in the population. The difference came about because this butterfly spent more time developing in an area of the habitat that is particularly warm and moist than other butterflies did. Do you expect the following generations to be composed of butterflies with larger wings?

A) Yes, this represents a genetic mutation that will be passed onto offspring.
B) Yes, this trait is advantageous so more butterflies will choose to develop in warm moist areas of the habitat.
C) No, this represents nonheritable variation caused by the environment.
D) No, this represents heritable variation but this trait does not increase ability to mate so will not be passed to the next generation.
