Can make a tremendous difference:-"Scientists at Rice University and the University of Washington (UW) this week unveiled a groundbreaking new method for detecting minute changes known as single nucleotide polymorphisms (SNPs) in the human genome. The human genome has more than 6 billion base pairs, and one of the revelations of modern genomics is that even the slightest change in the sequence—a single-nucleotide difference—can have profound effects."-"Scientists have sequenced the genomes of dozens of species, but those species-level genomes only tell part of the genetic story for a given individual. In people, for example, slight differences in just a few nucleotides can mean the difference between having green or brown eyes. This type of genetic variation within a species is called polymorphism, and SNPs are the smallest unit of polymorphic variation."-http://medicalxpress.com/news/2013-07-quadratic-smallest-genetic.html
