Which type of DNA sequence is more likely to show polymorphism?

Which type of DNA sequence is more likely to show polymorphism?
  1. Coding DNA sequence
  2. Non-coding DNA sequence
  3. DNA sequence in somatic cells
  4. DNA sequence in germ cells

Solution

The probability of variation to be observed in non-coding DNA sequence is higher as mutations in these sequences may not have any immediate effect/impact in an individual’s reproductive ability.
