Forensics Basics
A lie detector test is also known as
What is a polygraph
Stiffing of muscles after death
What is rigor mortis?
The process used to separate DNA fragments
What is gel electrophoresis?
Blood type known as universal recipient
What is AB+?
Can a fingerprint exclude a suspect?
What is yes?
This branch of forensic science studies insects to solve crimes
What is forensic entomology?
Settling of blood after death
What is livor mortis (lividity)?
Charge of DNA if it moves toward a positive end

Blood type as universal donor
What is O-?
Can a fingerprint help identify a suspect?
What is yes?
Evidence that includes witness statements or testimony
What is testimonial evidence?
Cooling of the body used to estimate time of death
What is algor mortis?
Percentage of DNA shared by all humans

Fingerprints are considered this type of evidence

The least reliable type of evidence often influenced by bias or memory
What is eyewitness testimony?
Tool and location used to take body temperature to determine time of death
What is thermometer in the liver
DNA fragments are separated based on this
What is size?
Something bloodstain analysis cannot determine
Who the blood belongs to (without DNA)?
Autopsies typically test for these three abnormalities
What are injury, disease, and toxins?
DNA evidence alone is not enough- this is why additional evidence is needed
What is to support/corroborate findings?
Why AB+ blood type known as the “universal recipient”?
What is, it has both A and B antigens, but no antibodies?
This makes each person's DNA unique
