Final answer:
DNA is used in forensics to identify individuals and establish relationships. It can match suspects' DNA with crime scene evidence and confirm or exclude biological relationships through analysis and comparison of specific DNA regions.
Step-by-step explanation:
DNA is used in forensics to identify individuals and establish relationships between individuals. DNA analysis can be used to match a suspect's DNA with evidence left at a crime scene. It can also be used to confirm or exclude a biological relationship, such as paternity or maternity testing. This is done by comparing specific regions of an individual's DNA to determine if they share common alleles.
For example, in a crime investigation, DNA samples can be collected from the crime scene and compared to DNA samples from potential suspects. If a match is found, it provides strong evidence linking the suspect to the crime. Similarly, in paternity testing, DNA samples from the alleged father, mother, and child are analyzed to determine if there is a biological relationship.
Overall, DNA analysis in forensics helps in identifying criminals, exonerating innocent individuals, and providing evidence in legal proceedings.
