Step-by-step explanation:

Mutation can be defined as any change in the genetic material of an organism.

This change may cause a corresponding change in the phenotype of the individual.

Mutations can occur spontaneously or induced.

Spontaneously, it occurs due to errors in DNA replication. And induced, when the organism is exposed to a mutagen, such as radiation.

Mutations can occur in somatic or germ cells.

In gene mutation there may be substitution, deletion or insertion of one or more bases in the DNA strand.

Chromosomal mutation refers to any change in the number or structure of chromosomes.
