After doing PCR on the same region between two individuals, you notice that each person's DNA yielded pieces of different sizes.
vitfil [10]

Answer:

C. This is an example of VNTRs.

Explanation:

VNTRs are Variable Number Tandem Repeats. These are short sequences of DNA repeated in tandem (that is, the sequences are repeated one next to the other) a certain number of times. Unrelated individuals have a different number of repetitions for a certain region of the DNA, therefore the total length of the fragment is variable among individuals, depending on how many times the short sequence is repeated.
