Answer:
Genetic testing, also known as DNA testing, is used to identify changes in DNA sequence or chromosome structure. Genetic testing can also include measuring the results of genetic changes, such as RNA analysis as an output of gene expression, or through biochemical analysis to measure specific protein output.[1] In a medical setting, genetic testing can be used to diagnose or rule out suspected genetic disorders, predict risks for specific conditions, or gain information that can be used to customize medical treatments based on an individual's genetic makeup.[1] Genetic testing can also be used to determine biological relatives, such as a child's parentage (genetic mother and father) through DNA paternity testing,[2] or be used to broadly predict an individual's ancestry.[3] Genetic testing of plants and animals can be used for similar reasons as in humans (e.g. to assess relatedness/ancestry or predict/diagnose genetic disorders),[4] to gain information used for selective breeding,[5] or for efforts to boost genetic diversity in endangered populations.[6]
