Genetic fingerprints can also be made from animals and plants as they also use DNA as their genetic blueprint. There are many practical uses for DNA fingerprinting. Scientists are using DNA fingerprints to assist in the conservation of endangered species. By fingerprinting the animals, it is possible to mate pairs who are less closely related. DNA fingerprinting can be used to identify inherited disorders in children, such as cystic fibrosis.
Early detection enables doctors to act quickly to treat the disease and reduce symptoms.
DNA fingerprints may also be useful in developing cures for inherited illnesses. Using this technique, it is possible to locate inherited disorders at the cell level. By studying the genetic fingerprints of relatives who have the same disorder, it becomes possible to identify DNA patterns associated with the disease in question. Identification is the first stage in developing a cure. A small sample, such as a square centimetre of leaf or a drop of blood is sufficient.
