Biological evidence, derived from testing samples of human tissues and fluids, that genetically links an offender to a crime is called what?

• A. Forensic biology
• B. Blood analysis
• C. Genetic profiling
• D. DNA evidence

Answer: (D)

The main concept is DNA evidence: it refers to genetic material obtained from biological samples like tissues and fluids that can establish a direct genetic link between a suspect and a crime. DNA is unique to nearly every individual, so analyzing a crime-scene sample and comparing it to a suspect’s DNA can confirm a match or rule out involvement. This makes DNA evidence the most precise form of linkage in forensics. Forensic biology is the broader field that studies such evidence, but the specific term for the evidence that provides the genetic link is DNA evidence. Blood analysis relies on blood types or serology rather than a unique genetic profile, and genetic profiling describes the process of generating a DNA profile, whereas the evidence itself that ties a person to the crime is DNA evidence.
