Answer: are the source of new genetic variation

Explanation:

Mutations are the alterations that occur in the genome of an organism.

  • The mutations can be caused either due to intrinsic factors such as replication error or extrinsic factors such as exposure to mutagens.
  • Genetic variations are the differences in the genome sequence of individuals in a given population and it occurs mainly due to two processes :

1. Mutation
