Concept:Mutation refers to a change in the genetic material, which directly involves the genotype of an organism.
Explanation:A mutation causes a permanent alteration in the DNA sequence.
Since DNA is the basic unit of the genotype, any change in DNA means the genotype is affected.
This change may or may not be visible in the phenotype.
For example, a mutation can be silent, producing no observable effect on the organism’s appearance.
Therefore, the statement that phenotype is not involved is incorrect because mutations can affect phenotype.
Also, mutations can occur naturally or be artificially induced by mutagens such as radiation and certain chemicals.
Hence, the statement that artificial induction is not possible is false.
The only correct and universally true statement is that genotype is involved in mutation.
Answer:D. Genotype is involved
