- The analysis of stains or substances of biological origin, such as blood, semen, vaginal fluid, and saliva
- Identification
- Polymorphic markers
As forensic DNA analysis became more commonplace (circa 1990), it began to replace the analysis of ABO type and polymorphic isoenzymes. For this to happen, forensic DNA analysis had to become:

2. Cheaper - The cost of forensic DNA analysis had to come down before it could displace the traditional typing m
