Genetics is the foundation for DNA testing. For paternity testing and other DNA testing, we turn to genetics to answer our questions about our biological relationships.

DNA testing is based on the process of genetic inheritance between parents and children. Children receive half of their DNA from their biological mothers and half from their biological fathers. DNA testing looks at the DNA profile of a child and compares it to the DNA profiles of both the mother and the father.

In a paternity test, the mother’s profile is used as a reference for half of the child’s DNA, while the alleged father’s profile is compared to the remainder of the child’s DNA. If the alleged father in the paternity test is the biological father, then child’s DNA will match the his DNA.

Occasionally, genetic mutations occur causing the child’s DNA not to match perfectly with the father or mother in a paternity test. In these cases, extended DNA testing is necessary. Our DNA testing laboratory is well-equipped to identify and handle such cases.
