allow individual organisms to evolve


are the source of new genetic variation


improve the survival of organisms

Answer 1

are the source of new genetic variation

Step-by-step explanation:

ok

Answer 2

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 :
