BBC News:耳屎的不同--基因ABCC11決定東亞人為幹耳屎/體味輕

研究說，亞洲人和非亞洲人的耳屎屬於兩種不同類型。亞洲人耳屎為幹耳屎，而其餘的大部分人為濕的。這取決於第16對染色體上的ABCC11基因。這個基因亞洲人，尤以東亞人（Chinese, Japanese and Korean individuals），與其他人種不一樣。這個基因也導致東亞人腋下味道沒那麽重。

Asian and non-Asian ears produce different types of earwax according to scientists at the Monell Institute in Philadelphia. Chromosome 16 is home to the "wet" or "dry" gene for earwax - with the wet variant dominating.

A small change in the gene ABCC11 is related to both the dry-type earwax and also for reduced underarm body odour found in Chinese, Japanese and Korean individuals.

The American study measured the concentration of 12 volatile organic compounds found in earwax - in groups of East Asian and white men.

In 11 out of the 12 compounds the Caucasian earwax had greater amounts of odorous compounds.
