Chicks atop a picture of a genetic map of a chicken. A genetic marker is a gene or DNA sequence with a known location on a chromosome that can be used to identify individuals or species. It can be described as a variation (which may arise due to mutation or alteration in the genomic loci) that can be observed.
In the example above, the three genotypes would be CC, CT and TT. Other types of genetic marker, such as microsatellites, can have more than two alleles, and thus many different genotypes. Penetrance is the proportion of individuals showing a specified genotype in their phenotype under a given set of environmental conditions.
