Mutations are rare, and occur because of _____.

an error in DNA replication
migration of organisms to a new population
a natural event, such as an earthquake

Respuesta :

Mutations result from an error in DNA replication, should it be from an alien source (like radiation) or simply a mistake in replication. Migration of organisms to a new population would alter the DNA by adding new genes, but it would not mutate them.
