The best possible way to test the paternity of a child would be to
a) compare the entire genome of the father and the child.
b) compare only a particular marker dna, which is present in both the genomes.
c) compare a small number of short sequences of dna derived from the father and the child’s genomes.
d) observe the number of complimentary base pairs formed between the father’s dna and the child’s dna.

The correct answer will be option-C

Explanation:

DNA is present in all the living organisms and in humans, 99.99% of the DNA is same in every individual with about. 0.10% difference in their genome.

This small percentage of DNA is unique to every individual and acts as the fingerprint (unique) of the gene of every individual. These differences are present in the form of mini-satellites.

The study of these mini-satellites helps the forensic scientist to study and compare the genome of two individuals. The comparison of the mini-satellites or short tandem repeats helps to test the paternity of the child.

Thus, Option-C is the correct answer.
