Genetic Map
A diagram showing the relative sequence and position
of specific genes along a chromosome (DNA) molecule. Markers utilized as "signpsts"/guideposts in such maps include single-nucleotide polymorphisms (SNPs), restriction sites (i.e., the specific locations where each restriction endonuclease "cuts" a DNA strand), and microsatellites. Such markers located in or close to the gene of interest [e.g., a disease-causing gene within a chromosome] to a researcher are more likely to be inherited along with that gene.
