Due to single nucleotide polymorphisms SNPs),all humans have a slightly different nucleotide sequence for their genome.Restriction mapping is used in forensic sciences to match DNA evidence to a potential suspect of a crime.How does restriction mapping reduce the likelihood of misidentifying a suspect?
A)SNPs change the genes that are expressed
B)SNPs only remove restriction sites from the genome resulting in a unique "fingerprint" for each person
C)SNPs add and remove restriction sites resulting in a unique "fingerprint" for each person
D)SNPs only add new restriction sites to the genome resulting in a unique "fingerprint" for each person

SNPs can add or remove restriction sites from the genome, which means that each person will have a unique set of restriction sites that can be identified through restriction mapping. Therefore, it reduces the likelihood of misidentifying a suspect by comparing the pattern of restriction sites in the DNA evidence to that of the potential suspect.
