  • The characters that are transmitted from parents to offspring during reproduction show similarities with the parents because the offspring inherit them from their parents.
  • But, copying of DNA is a biochemical process, which is not absolutely reliable.
  • Therefore, it is only to be expected that the process of copying the DNA will have some variations each time.
  • As a result, the DNA copies generated will be similar, but may not be identical to the original DNA from parents.

So, the correct option is C.
