DNA Fingerprinting

What is DNA Fingerprinting?
Well DNA is the carrier of genetic information. So DNA fingerprinting, which is also known as DNA typing, is a DNA-based identification that relies on genetic differences among individuals or organisms.
What is DNA Fingerprinting used for?
The test is used to determine whether a family relationship exists between two people, to identify organisms causing a disease, and to solve crimes. Only a small sample of cells is needed for DNA fingerprinting.
Family Tree
The people from the same family (usually the children of two people) have similar DNA fingerprints as eachother.
DNA fingerprint cells
These are DNA cells from your fingerprint. Scientists and detectives only use a tiny bit of them since that is all they need to get the perfect results.
Crime Scene
DNA fingerprints are used to catch the criminals that have commited a crime. They try to get any DNA left at the crime scene in order to match the victim and the suspects to real people.
Who discovered DNA Fingerprinting?
In September 1984, a geneticist from the University of Leicester in Great Britain, named Dr. Alec Jeffreys, was studying hereditary diseases in families. He was focusing on methods to resolve paternity and immigration disputes by demonstrating the genetic links between individuals. He ended up developing techniques for DNA Fingerprinting.
