genetic marker

A gene, DNA sequence, or gene product whose inheritance can be traced through a pedigree or phylogeny. Genetic markers are used in paternity testing, studies of evolution, and evaluating genetic contributions to phenotypes including disease. Genetic markers associated with certain diseases can often be detected in the blood serum, where their presence is used to determine whether a person is at high risk for developing a disease.

genetic marker

(Genetics) a gene with two or more alternative forms, producing readily identifiable variations in a particular character, used in studies of linkage, genetic mapping, and identification of the presence of other genes that are closely linked to, and therefore usually inherited with, it
