Earwax comes in two types, dry and wet, which is determined by a single gene; this page reviews the evidence.

Unlike most of the human characters that are used to demonstrate simple genetics principles, wet vs. dry earwax really is controlled by one gene with two alleles. Several factors make it especially attractive as a classroom topic: the gene has been identified, the biochemical basis for the variation is fairly well understood, there is evidence for strong natural selection, and there are links to human health (body odor and possibly cancer).

There are, however, two problems with using earwax type in classroom exercises. One is that the allele for dry earwax has a frequency in western European populations of 10 to 20 percent, and it is virtually absent from African populations. Because dry earwax is recessive, this means that a classroom of students of European and African ancestry may show no variation; everyone could have wet earwax. Classrooms in northern China or Korea, on the other hand, may contain only students with dry earwax, because the allele for dry earwax is at nearly 100 percent in those areas.

The second problem with using earwax type in a genetics exercise is that having a bunch of students sitting in a classroom, digging wax out of their ears and waving it around, would be kind of disgusting.

Die versteckte Gefahr der Wattestäbchen: Warum die Ohrenreinigung oft schadet

Der alltägliche Griff zum Wattestäbchen und seine Folgen Kaum eine Handlung im Bereich der Körperpflege wird so selbstverständlich durchgeführt wie die Reinigung der Ohren mit Wattestäbchen. Viele Menschen empfinden ein angenehmes Gefühl der Sauberkeit, wenn sie nach dem Duschen oder am Morgen routinemäßig den Gehörgang säubern. Doch was auf den ersten Blick hygienisch erscheint, entpuppt sich bei genauerer Betrachtung als kontraproduktive Maßnahme, die mehr Schaden anrichtet als Nutzen bringt. Die vermeintliche Reinigung bewirkt tatsächlich das Gegenteil dessen, was beabsichtigt ist. Der Mechanismus der Ohrenselbstreinigung Um zu verstehen, warum Wattestäbchen problematisch sind, lohnt ein Blick auf die natürlichen Vorgänge im Ohr. https://www.unserneueswir.de/?p=7565 Read the full article

When it comes to ear health, one topic that often gets overlooked — until it becomes a problem — is ear wax. It's something we all deal with, but many of us don’t really understand its role, or the safest ways to manage it. If you use hearing aids, like I do, staying on top of ear wax build-up is especially important.
