A mother has a child and wishes to know if a man (the alleged father) is the biological father of the child. But, this alleged father is missing, unavailable, or deceased. If the alleged father's biological parents (i.e., the child's alleged paternal grandparents) are available, however, a profile can be derived from their DNA patterns that can then be used to test paternity of the missing alleged father. In this case, the ideal situation is to submit samples from the mother, child, and both alleged paternal grandparents. It is also possible to conduct this testing with only the child and both alleged paternal grandparents (mother excluded), but this should only be done when the mother is not available.
