No Single Gene For Eye Color, Researchers Prove

Since I wrote a little about eye color before, I think I ought to clarify some things. The earlier article was really about how recessive and dominant genes can have an indirect effect on social behavior via evolution. But the truth about the genetics of eye color is actually somewhat more complicated:

No Single Gene For Eye Color, Researchers Prove
A study by researchers from The University of Queensland's Institute for Molecular Bioscience (IMB) and the Queensland Institute of Medical Research is the first to prove conclusively that there is no single gene for eye colour.

Instead, it found that several genes determine the colour of an individual's eyes, although some have more influence than others.

Update 8/3/08: There is more recent news on this subject here.
