https://en.wikipedia.org/wiki/Body_odorThe non-functional ABCC11 allele is predominant among East Asians (80–95%), but very low in other ancestral groups (0–3%).[5] Most of the world's population have the gene that codes for the wet-type earwax and normal body odor; however, East Asians are genetically predisposed for the allele associated with the dry-type earwax and a reduction in body odor.[5][19][21] East Asians (Chinese, Koreans, and Japanese) have fewer apocrine sweat glands compared to people of other descent, making East Asians less prone to body odor.[23][24] The reduction in body odor and sweating may be due to adaptation to colder climates by their ancient Northeast Asian ancestors.[19]
