genetic marker

a gene or segment of DNA with an identifiable location on a chromosome and whose inheritance can be readily tracked through different generations. Because DNA segments that lie near each other on a chromosome tend to be inherited together, markers are often used to determine the inheritance of a gene that has not yet been identified but whose approximate location is known.
