Detailed explanation-1: -Sequence polymorphisms, which are tiny sequence variations (usually single base-pair changes) within individuals, are used in DNA fingerprinting. Based on the position of restriction sites in the genome, restriction enzymes can digest the entire genome into DNA fragments of a specific length.
Detailed explanation-2: -DNA fingerprinting is a laboratory technique used to determine the probable identity of a person based on the nucleotide sequences of certain regions of human DNA that are unique to individuals.
Detailed explanation-3: -Polymorphism, as related to genomics, refers to the presence of two or more variant forms of a specific DNA sequence that can occur among different individuals or populations. The most common type of polymorphism involves variation at a single nucleotide (also called a single-nucleotide polymorphism, or SNP).
