Moreover, not all recorded fathers are the biological fathers. Since such a large percentage of children are born to single mothers, oftentimes many of them end up being a part of some courtroom fight over compensation and custody issues. Frequently, the court has no choice other than to test for paternity.Test for paternity through DNA matching techniques has by far been the most effective and reliable factor in determining the biological identity of a child's father.
