Ksivusya [100]

Answer;

Yes. The benefit of a mutation can help it survive in a particular environment.

Explanation;

-Mutations are changes in the genetic code of an organism. There are different types if mutations, and they typically occur when DNA is being replicated and something goes wrong during the replication process, causing a base pair or set of base pairs to be changed somewhere in the DNA strand.

-Though mutations can be harmful, mutations can also be beneficial. In fact, beneficial mutations are the basis for evolution. When a mutation occurs that makes an organism better suited for its environment, then the organism is better able to survive and reproduce and the mutation can be passed along to the organism's offspring. This type of actively beneficial mutation is rare, but it does occur.
