... Autosomal traits are controlled by genes on one of the 22 human autosomes. Consider earlobe attachment. A single autosomal gene with two alleles determines whether you have attached earlobes or free-hanging earlobes. The allele for free-hanging earlobes (F) is dominant to the allele for attached ear ...

Lactose tolerance
... This can be referred to as lactase nonpersistance, adult hypolactasia or, more commonly, lactose intolerance. When a lactose-intolerant adult ingests a large amount of lactose, it passes into their gut without being broken down. The bacteria in the gut then react to the raised lactose levels by shif ...
