Markers
for Single Nucleotide Polymorphism (SNP) Single Nucleotide Polymorphism (SNP) markers are short sequences of DNA that can be used to identify genetic variations within a population. SNPs occur when a single nucleotide in a person's genome differs from the standard reference sequence and may be the cause of a genetic difference or trait. SNP markers can be used to identify and track individual characteristics, such as disease-causing mutations, among individuals within a population. They also allow researchers to study the genetic relationships between populations and to identify common ancestry and genetic traits. SNP markers are useful tools in medical research and have been used in the development of personalized medicine, genetic tests, and in understanding the genetic basis of complex diseases.
