Why is DNA profiling used?

It's a forensic method used in criminal investigations, parentage testing, immigration eligibility determination, genealogical and medical research, and population studies in zoology, botany, and agriculture.

DNA profiling, in particular, can be used to identify suspects from evidence found at the crime scene, confirm an individual's biological parents or siblings, determine the paternity or maternal twins, and assist in the criminal justice system.

DNA profiling is used for identifying individuals, determining familial relationships, and solving crimes. It provides a unique genetic fingerprint that can differentiate individuals based on their DNA sequences. This technology is highly accurate and reliable, making it valuable in forensic investigations, paternity testing, and establishing biological relationships in various fields such as medicine, anthropology, and conservation biology. Additionally, DNA profiling can help identify genetic predispositions to diseases and assist in personalized medicine.
