C/CPublished research associates this genotype with wet-type earwax and typical underarm body odor / apocrine sweat gland activity.
C/TOne copy of each allele. Published research associates this genotype with wet-type earwax, similar to C/C.
T/TPublished research associates this genotype with dry, flaky earwax and reduced underarm body odor — this variant is common in East Asian populations and is one of the best-characterized examples of a single gene controlling multiple visible traits.
