The testing of the alleged father and child or children is the more common way of carrying out a DNA paternity with around 80% of tests being done without the mother’s DNA samples; this is called motherless testing. The results will be equally reliable with or without the mother’s samples and in some cases a father may wish to conduct a test without the mother knowing. Having the mothers sample helps laboratories exclude her share in the Childs genetic inheritance, and thus focus solely on the genetic inheritance of the father and the child. Issues come into play if the child is a minor, as in such cases a legal guardian of the child has to sign the submission form.
