Answer
An SNP or single nucleotide polymorphism is a single nucleotide that is different from a collection of others in a population. These can be used to locate mutant genes because they are genetic markers. If an SNP is found it can be traced and the surrounding genes can be analyzed for mutations.
Work Step by Step
An SNP is detected by gene sequencing or oligonucleotide, and serves as a signal in our chromosomes. This signal indicates that somewhere in that region there is a mutation. In this way, we are using an SNP to track our gene linkage.
