Q: What is a random change in an organism's genes?


Read this paragraph and choose the correct option from the provided answers:

At some time in the past, a variation probably came from a mutation. A mutation is a random change in an organism's genes ( Figure below ). Mutations are natural. Some are harmful, but many are neutral. If a mutation is harmful, the organism may not live to reproduce. If the mutation is beneficial, that organism may have a better chance to survive. An organism that survives is likely to have offspring. If it does, it may pass the mutation on to its offspring. The offspring may be more likely to survive.

 Choices:

- meiosis

- infection

- accumulation

- mutation


A:
mutation
