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 a procedure in which tissue samples are taken from the mother, the alleged father and the child. If the genetic tests show a 99% or greater probability that the male is the biological father of the child, then our hearing officer will issue an order establishing paternity. The CSEA will send the genetic test results to you by mail. Genetic test results will not be released to anyone over the telephone.
