Genetic profiling is a scientific technique used to identify an individual's unique genetic makeup. It involves analyzing specific regions of DNA to create a genetic fingerprint, which can be used for various purposes, including forensic investigations, paternity testing, and medical diagnostics. This process helps in understanding genetic predispositions to certain diseases and can guide personalized treatment options. The technology behind genetic profiling relies on methods such as polymerase chain reaction (PCR) and DNA sequencing. These techniques allow scientists to examine variations in genes, known as polymorphisms, which can provide insights into an individual's ancestry and health risks.
