Answer:Single nucleotide polymorphisms or SNPs (pronounced "snips") are DNA
sequence variations that occur when a single nucleotide (A,T,C, or G) in the
genome sequence is altered (point mutation).
SNPs do not cause disease, but they can help determine the likelihood that someone will develop a particular disease.
Because single base mutations can either create additional restriction sites or destroy pre-existing sites, DNA preparations from different individuals frequently exhibit different patterns of size distribution of restriction fragments that hybridize with a particular probe. These differences are called
restriction fragment length polymorphisms (RFLPs).
