Can a Test be Done if the Alleged Father is Missing or Deceased?
Yes. Paternity testing can still be performed, although the test will involve more analysis. If the alleged father is unavailable, testing involving grandparents is possible. In this situation, samples are collected from the alleged paternal grandparents and analysis is performed to determine if they are excluded from grandparentage. If not, the chance the alleged grandparents transmitted the genes to their son is calculated and used to determine the probability of paternity. If the alleged paternal grandparents are unavailable, testing can be performed on the alleged father’s siblings or other offspring, although the evidence supporting the probability of paternity is not as strong.
