A DNA test can be performed
by testing the blood or a cheek swab
. A blood test uses Restriction Fragment Length Polymorphism (RFLP) to compare the father’s DNA with the DNA of the child. A cheek swab uses a buccal smear to collect cells inside the cheek to test for DNA. These tests provide a DNA sample for testing.
How does a paternity test prove who the father is?
Deoxyribonucleic acid, or DNA, is the genetic material you inherit from your mother and father. Paternity refers to fatherhood. A DNA paternity test
uses DNA, usually taken from a cheek swab
