When is a DNA mutation referred to as a DNA polymorphism?

When is a DNA mutation referred to as a DNA polymorphism?
  1. When the mutation is not inheritable
  2. When the mutation occurs in coding DNA sequence
  3. When more than one variant at a locus occurs in a population with a frequency greater than 0.01
  4. When the mutation occurs in non-coding DNA sequence

Solution

Allelic sequence variation is traditionally described as a DNA polymorphism if more than one variant at a locus occurs in the human population with a frequency greater than 0.01.
