Answer:
are the source of new genetic variation
Step-by-step explanation:
The concept of mutation is related to the modification of genetic material. Any kind of change, be it in the organization or in number, will result in a new genotype and character.
The importance of mutation lies in the fact that it is precisely that that guarantees the modifications of species, since it is only through a mutation that new genes can emerge. This is why mutations are important and considered the basis for the evolution of species in all populations.
