A trait useful in one environment may not be useful in another. What is the reason?

Answer and explanation

Correct answer: The advantage of a trait depends on the environment

The adaptive value of a trait depends on the environmental conditions in which an organism lives. A thick coat may help an animal survive in a cold region but become disadvantageous in a hot region. Since natural selection favors traits that improve survival and reproduction under local conditions, the same trait can be useful in one environment and neutral or harmful in another. Option A is correct.
