A polymorphism is distinguished from a mutation in what way?

Question

Quizplus · Accepted Answer

A polymorphism is a genetic variant present in at least 1% of a population. Mutations are rare genetic changes that occur at a low frequency in a population. Therefore, the main distinguishing feature between a polymorphism and a mutation is their frequency in the population.

Answer: B, C, and D are not correct. The size of the genetic region involved does not distinguish between a polymorphism and a mutation, as both can occur at any size of a genetic region. The severity of effect on phenotype also does not necessarily distinguish between the two, as some mutations can be silent or have minimal effects, while some polymorphisms can have a significant effect on phenotype. Associations with other genetic events are also not a distinguishing feature, as both polymorphisms and mutations can occur alone or in association with other genetic events.
