Mapping of the wet/dry earwax locus to the pericentromeric region of chromosome 16.

Human earwax is a one-gene trait comprising two phenotypically distinct forms--wet and dry. This trait is attributed to secretory products of the ceruminous apocrine glands, and frequencies of phenotypes vary between ethnic groups. We did linkage analysis of eight Japanese families segregating earwax dimorphism.
