An Explanation of Genetic Material. One of the types of paternity tests available is a DNA test. Deoxyribonucleic Acid (DNA), is the genetic material present in every cell of the human body. Half of a child’s genetic material is from his or her biological mother and half from the biological father. The process of DNA testing compares the genetic characteristics of the child to those of the mother. The characteristics that cannot be found in the mother have to have been inherited from the father.
DNA Paternity Testing. The most accurate form of paternity testing possible is DNA testing. An alleged father can be completely ruled out if DNA patterns between the child and the alleged father do not match on two or more DNA probes. However, if the DNA patterns between mother, child, and the alleged father match on every DNA the likelihood of paternity is 99.9 percent. The test can be conducted from a blood sample or a Buccal strap in which a swab is rubbed against the inside of the subject’s cheek.
