Forensic genetics is a branch of science that applies genetic analysis to legal investigations. It involves examining DNA from various sources, such as blood, hair, or skin cells, to identify individuals involved in a crime. This technique is crucial in solving cases, exonerating the innocent, and identifying victims. The process typically includes collecting samples, amplifying DNA using techniques like PCR (Polymerase Chain Reaction), and comparing genetic profiles. Forensic genetics has revolutionized criminal justice by providing reliable evidence, making it an essential tool for law enforcement and legal professionals in solving crimes and ensuring justice.
