DNA Mutations

Question 6 • WI-Grade 8 Life Science A

Which mutation is beneficial?

Answer
A
one that changes the color of a rabbit, allowing it to hide from predators
B
one that results in lighter flower petal colors without changing the plant’s ability to reproduce
C
one that causes a person’s body to produce thick mucus that clogs the lungs
D
one that makes it easier for a corn plant to contract a disease

Explanation

A beneficial mutation improves an organism’s chances of surviving or reproducing. A rabbit whose color helps it hide from predators is less likely to be eaten, so this mutation can improve its survival. The other choices are neutral or harmful: they do not improve reproduction or make survival more likely.
