Which evidence best supports the claim that mutations are a source of inheritable genetic variation?(1 point)

1 Mutations affect the way DNA is created through transcription.
2 Mutations can only happen during meiosis because genes are inherited.
3 Mutations affect protein synthesis which impacts the way traits are expressed.
4 Mutations are not inheritable from gametes because they are given from each parent.

The evidence that best supports the claim that mutations are a source of inheritable genetic variation is:

3 Mutations affect protein synthesis which impacts the way traits are expressed.
