Forensic biology involves identifying biological samples; such as blood, semen and saliva. There is some degree of overlap with forensic medical specialists and pathologists who examine the effect of trauma to the person, the biologist examining where the tissue has been deposited, and the identification of trace evidence. The forensic biologist’s role may involve:
• Identification and characterization of samples – Including blood, semen, saliva and other biological substances using various tests (chemical, microscopic, and immunology.
• Individualization of samples – by DNA profiling.
• Blood spatter Interpretation – to determine how stain was produced.
• Clothing damage analysis.
• Identification of weapons.
