SNP: single nucleotide polymorphism
•DNA single base
variations found in >1% of population.
•Abundant: ~15
million per human genome.
•Distribution
throughout the genome and with high density.
•More stable and
easy to assay compared with microsatellites.
•Potential
biallelic markers
•Functional
variants: cSNP and rSNP (5% of all SNP).
