Industry:Anthropology
A unit of inheritance usually occurring at a specific location, or loci, on a chromosome. Physically, a gene is a sequence of DNA bases that specify the order of amino acids in a protein or, in some cases, a small RNA molecule referred to as a microRNA. A gene may be made up of hundreds to thousands of DNA bases. Genes are responsible for hereditary characteristics.

Advocates of this approach incorrectly believe that there are more or less distinct populations of people from different geographic regions. Negroid, Mongoloid, and Caucasoid are examples of typological groupings.
