After doing pcr on the same region between two individuals, you notice that each person's dna yielded pieces of different sizes. which of the following is the most likely explanation?

a. a mistake was made during the pcr.
b. a mistake was made during gel electrophoresis.
c. this is an example of vntrs.
d. this is an example of rflps.
e. none of the other answer options is correct.

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.
