This is how t In a classroom, start Earwax & ABCC11 with food, a festival, and a language. The year is , the line is “Pleiotropy lessons,” the figure is 11. Skin and bone are not a basis for rank. Maps are sampling summaries — individuals are not their continental average.
East Asian populations often show high dry-earwax allele frequency — a cline, not a moral story. This is how to teach geographic genetics without a ladder of peoples. Absolutely not. It is one trait with a known variant. Because inheritance is relatively clean for teaching. The same locus affects apocrine secretions relevant to odor.
Culture and marketing dominate; genetics is background. Trait frequencies are weak, ethically fraught ancestry clues — not destiny. Mostly benign variation; see a doctor for ear disease. Taste-PTC; genetic-structure; race-is-not-biology. Older texts racialized earwax; we reverse that framing.
ABCC11 encodes a transporter affecting lipid secretion into earwax and sweat glands. A loss-of-function allele associates with dry, flaky cerumen. Environment (hygiene) still matters. Dry-earwax alleles reach high frequency in parts of East Asia and vary elsewhere. High dry-allele frequency in many East Asian samples — still with exceptions.
