DNA paternity testing is a reliable and powerful method of proving and disproving parentage. The test is based on accurate analysis of the genetic profiles of the mother, child and alleged father. Deoxyribonucleic acid (DNA), the unique genetic blueprint within each nucleated cell of a person’s body determines the genetic pattern and individual characteristics. A child inherits half of this DNA pattern from the mother and half from the father. If the mother’s and child’s patterns are known, the father’s can be deduced with virtual certainty.
