Genetic Marker
A genetic marker is a DNA sequence with a known physical location on a chromosome. Genetic markers can help link an inherited disease with the responsible gene.
Genetic Markers
Genetic epidemiologists like King construct pedigrees of families that have multiple cases of breast cancer across generations, often locating the families with the help of physicians treating the women.
Genetic marker
A locus that has a useful phenotype which can be used for genetic selections or screens.
Genetic polymorphism
The existence of two or more genetically different classes within a population.
Genetic marker A polymorphic locus which can be used in linkage studies. The polymorphism may be anything to do with the DNA at the locus or its possible product so long as it can be recognised with an appropriate test.
Genetic marker. A gene or group of genes used to "mark" or track the action of microbes.
Genome. The genetic complement contained in the chromosomes of a given organism, usually the haploid chromosome state.
Genetic marker: A known site on the chromosome. It might for example be the site of a locus with some recognizable phenotype, or it may be the site of a polymorphism that can be experimentally discerned. See 'Microsatellite', 'SNP', 'Genotyping'.

The unfortunate use of ‘carrier' to describe individuals positive for a genetic marker is wrong, and the use of ‘carrier frequency' in that context should be replaced by ‘marker frequency'.
