DNA PATERNITY TESTING
Throughout history people have used physical characteristics to identify others. Physical characteristics, however, can be disguised.
There are many blonde hair blue eyes men.
Coloured contact lenses can be used to disguise eye colour.
Hair can be coloured, and even skin can be artifically darkened.
Science now offers a way to help.
Do these two samples come from the same person?
Forensic testing examines the chromosomes from the samples identifying values in the DNA chain. These values are compared to establish if the samples came from the same person.
The DNA molecules contain the coding for our bodies. Each gene provides the blueprint for one thing, for example, hair colour.
Some examples where Forensic and Paternity testing can be used:
* Semen detection on underwear for suspected infidelity.
* Paternity disputes.
* Suspected incest paternity.
* Insurance company fraud investigations when the actual driver in a vehicle accident is in question.
* Criminal matters.
