Concept / ApproachA mutation is a heritable alteration in DNA (gene or chromosome), not merely a transient environmental effect or ordinary recombination. Common pitfalls Confusing gene mutation with recombination or phenotypic plasticity. Final AnswerA sudden heritable change in DNA is a mutation.

Genetics — definition check: What is a mutation in classical genetics? Frame the answer in terms of heritability and changes to genetic material, not recombination or environmental effects. Choose the correct definition.

Difficulty: Easy

A sudden heritable change in the genetic material (DNA) of an organism
A temporary change in phenotype due to environment (no DNA change)
The reshuffling of existing alleles during meiosis (recombination)
A change in behavior due to learning and experience

Correct Answer: A sudden heritable change in the genetic material (DNA) of an organism

Explanation:

Concept / ApproachA mutation is a heritable alteration in DNA (gene or chromosome), not merely a transient environmental effect or ordinary recombination.

Common pitfalls

Confusing gene mutation with recombination or phenotypic plasticity.

Final AnswerA sudden heritable change in DNA is a mutation.
