A process in which a small section of fluorescently labeled DNA (a DNA probe) is linked with (hybridized to) the DNA from a chromosome of interest. This technique is used to identify the location of specific genes on chromosomes or areas in which chromosomes have been damaged or duplicated. FISH is used in amniocentesis to analyze retrieved fetal cells for evidence of specific genetic anomalies such as trisomy.
