Talk:Glossary of Genetic Terms and Concepts
Allele: A "variant" or alternative form of a gene in a specific location on a chromosome. Sometimes scientist refer to allelic frequency, which means how often that alternative version of the gene is observed.
Assay: A controlled experimental procedure for detecting, measuring, or quantifying the biological activity of a molecule or cell function. There are hundreds of different assay types and technologies in use today.
Genotype: An individual's entire genetic makeup. Sometime a disease or condition is referred to as having a specific genotype (i.e., cancer genotype). A genotype typically implies a measurement of how an individual's genetic constitution differs from a group or category of disease.
