Paternity means fatherhood.
Paternity is established when a paternity testing laboratory uses genetic testing methods to demonstrate, to a legal standard, that an alleged father is the biological father. Paternity is disproved when these same methods and standards demonstrate that an alleged father is not the biological father. DNA analysis, which is a major advance in the field of paternity testing, involves the direct examination of the genetic material that a child inherited from its biological parents. DNA is located throughout the human body and in the same identical form. Thus, DNA in blood is the same as that in skin, cheek lining, muscle, bone, teeth and various other tissues.
