In genetics, a biomarker (identified as genetic marker) is a DNA sequence that causes disease or is associated with susceptibility to disease. They can be used to create genetic maps of whatever organism is being studied.ne example of a commonly used biomarker in medicine is prostate-specific antigen (PSA). This marker can be measured as a proxy of prostate size with rapid changes potentially indicating cancer.
CHEMICAL AND MOLECULAR MARKERS. A genetic marker is any visible character or otherwise assayable phenotype, for which. alleles at individual loci segregate in a Mendelian manner. Genetic markers can be used to. study the genetics of organisms, including trees, at the level of single genes. The develop-. ment of the discipline of genetics would not have been possible without genetic markers. such as the visible characters in peas and Drosophila.
