DNA fingerprinting is used to determine paternity, in forensic crime analysis, in population genetics to analyze variation within populations or ethnic groups, in conservation biology to study the genetic variability of endangered species, to test for the presence of specific pathogens in food sources, to detect genetically modified organisms either within plants or food products, in evolutionary biology to compare DNA extracts from fossils to modern-day counterparts, and in the identification of victims of a disaster.
