Brown-Eyed Genes

Researchers from the University of Fukui genotyped five SNPs in the OCA2 and HERC2 genes associated with eye color in a Japanese population and compared the haplotype distribution to those of African and European populations. In Cell Biochemistry and Function, they say the most common haplotype in the Japanese population (all brown-eyed) was A-GAG and that haplotype is rare in Europeans, even amongst brown people. At Gene Expression Razib dives a bit deeper into the paper and maps out the frequencies of the SNPs world-wide.
