SINGLE NUCLEOTIDE POLYMORPHISM

• On average, SNPs will occur in an organism’s DNA more than 1% of the time. Because only about 3% to 5% of an organism’s DNA codes for proteins, most SNPs are found outside the regions of genes of interest.
• SNPs found in a gene of interest are of particular interest to researchers because they are directly associated with a desired trait. Because of the recent advances in technology, SNPs are playing a greater role in selection and diagnosis of genetic traits.
