Colligative properties are those properties of solutions that depend on the number of dissolved particles in solution, but not on the identities of the solutes. For example, the freezing point of salt water is lower than that of pure water, due to the presence of the salt dissolved in the water.
Shares & Saves. Save. DNA testing evolved from the study of genetics, which began in the late 1800s when Gregor Mendel first studied the phenomenon of inherited traits in pea plants. His work laid the foundation for the discovery of DNA, or deoxyribonucleic acid, the molecules that contain our genetic makeup.
Genetic testing is the process of using medical tests to look for changes (mutations) in a personâs genes or chromosomes. Hundreds of different genetic tests are used today, and more are being developed. Genetic testing for diseases that can be inherited Genetic testing can be used in different situations.The type of testing most often used to check for cancer risk is called predictive gene testing. Itâs used to look for gene mutations that might put a person at risk of getting a disease.he obvious benefit of genetic testing is the chance for a better understanding of your risk for a certain disease. Testing is not perfect, but it can often help you make decisions about your health. A negative result on a genetic test in families at risk for a specific cancer may help relieve anxiety or uncertainty.
