Glossary

Based on Mendel's work, science first answered paternity questions by looking at blood type - a trait with inheritance patterns similar to that of flower color in pea plants. Before DNA, blood offered the best clues for answering paternity test questions and included methods like ABO blood typing, Serology, and HLA testing.
