What does the letters SNP stand for.
SNP: SNP stands for single nucleotide polymorphism. SNPs - pronounced "snips"
- are common, but minute, variations that occur in the human genome at a
frequency of one in every 300 bases. That means 10 million positions out of the 3
billion base-pair human genome have common variations. These variations can be
used to track inheritance in families and susceptibility to disease, so
scientists are working hard to develop a catalogue of SNPs as a tool to use in
their efforts to uncover the causes of common illness like diabetes or heart
