SNiPs Strike again
As previously covered in The Han-Man's great piece about single nucleotide polymorphisms, SNPs are single nucleotide variations that often define the observable genetic differences between individuals (ie: like hair colour, and eye colour).
Although the basic understanding of genetics and heredity is probably safe, there is some new information regarding eye colour SNPs that may cause a few folks with genetics training to take a closer look. Then again, this 'new info' isn't really all that strange either.
Basically it's all about a spectrum of variability for eye colour, which I think is really only a specialization of the age-old "blue->recessive/brown->dominant" adage.
