Japanese map of the earwax gene frequency: a nationwide collaborative study by Super Science High School Consortium.
Journal of human genetics - 1 Sept 2009
Abstract excerpt
Wet/dry types of earwax are determined by the c.538G>A single-nucleotide polymorphism (SNP) in the ABCC11 gene; GA and GG genotypes give the wet type and AA the dry type. The Japanese population may have a dual structure comprising descendants of mixtures between the ancient 'Jomon' and 'Yayoi' populations. We hypothesized that the dry type was introduced by the Yayoi people to the Jomon population where the wet...
