Mention any two ways in which single Nucleotide Polyrmorphism (SNPS) identified in human genome can bring revolutionary change in biological and-medical sciences.

A single-nucleotide polymorphism, often abbreviated to SNPs, is a variation in a single nucleotide that occurs at a specific position in the genome, where each variation is present to some appreciable degree within a population (e.g. > 1%).
For example, at a specific base position in the human genome, the C nucleotide may appear in most individuals, but in a minority of individuals, the position is occupied by an A. This means that there is a SNP at this specific position, and the two possible nucleotide variations – C or A – are said to be alleles for this position.
